Doug, It’s certainly possible, but less efficient. There are power losses when inverting dc to ac, and when converting ac to dc, and you would be doing both. For example; say the inverter and charger were each 90% efficient, then you would have a collective 80% efficiency (actually somewhat less if you do the math). Your modern equipment is probably more efficient than that, but you get my point. I’d also check the Duty Cycle of the Ford’s inverter to assure it’s rated for continuous operation. Cheers! Geoff

Now Jd, where are those safety jack stands you talk about? Just teasing, I think you're perfectly safe using the stabilizer jacks! I was just wondering though, are you replacing the spring links? I've noticed that a couple of mine are not accepting grease anymore, even though I replaced the zerks. Do you think that they should be replaced after 25k miles? Geoff

Thanks for the nice words JD! Yes, one of the travelers is always hot, and the pump is grounded separately. My referenced sketch shows standard 3-way wiring for simplicity, with the (+) on one end of the circuit, and the switch leg (feed to pump) on the other. The Oliver is wired as a "dead end" 3-way switch, where both the hot (+) and the pump feed come to the main switch location, and bathroom is the dead end with the red point wire doubling back and being spliced to the pump feed at the main switch location. It doesn't matter how the travelers are connected, or if they are reversed. One or the other, or both, switches will always be in the physical On or Off position with the pump running. You may be curiously interested in how three or more switches (4-way switches) work in this 3-way circuit. The travelers will switched to run straight through, or they will be switched to Criss Cross each other. Clever! This is also illustrated in my referenced sketch! Cheers! Geoff

This is a Double Pole Double Throw (DPDT) switch, and only one pole is being used (the right side as the photo shows.) The left is identical in function. Being a Double Throw, the centre tab is common, and it closes the circuit to the top tab when switched up, and to the bottom tab when switched down. The red wire is the common, sometimes called the Point wire (either a hot or switch leg,) and the brown wires are often called travelers. One or the other brown wires will become hot depending on switch position. The switch on the other end is the same, so that either switch can energize or de-energize either brown wire and power the pump. No ground wires are involved in these switches. I provided a wiring sketch for these switches in a modification titled: 4-way pump switch for outdoor shower. It shows the wiring diagram for the switches, and the addition a third (4-way) switch to turn the pump on/off from the outdoor shower. https://olivertraveltrailers.com/forums/topic/10604-4-way-pump-switch-for-outdoor-shower/ Hope that helps to clear up these confusing switches! Cheers! Geoff

Joshua Tree is like visiting the Flintstones back yard! It should be a bucket list park. I'm pretty sure we stayed in that very same site. We had to reserve two different sites because of limited availability. Our first site was a 20 point turn to squeeze in, and then some kind folks suggested that we look at google satellite maps when reserving a site. This proved to be a great tip! Cheers Geoff

Watched a new video from around July 2025. It's an interesting comparison from an Airstream Basecamp guy who thoroughly praised the Oliver as the highest quality trailer he's seen. The video also shows some of newer equipment such as the Truma AC, and the interior equipment spaces including what appears to be a Victron 30 amp DC to DC charger installation. Actually a friend sent this and I couldn't help feeling proud! Cheers, Geoff

@jd1923 and @Ronbrink. I took another look at the Beech Lane picture showing the fans mounted with the their special hardware to the louvers of a large vent cover that's very similar to the Norcold’s lower vent. I guess that’s where I got the idea that they were meant to go in the lower vent. But the picture’s caption says “it pulls air through,” which implies that it’s sucking air out of the cavity. . . which means they would be sucking against the natural convection flow if mounted in the Norcold’s lower vent? Humph! I was also thrown by the sweep, pitch and spinning direction of these fan blades. They’re similar to a boat propeller, leading one to think that they move air in the same direction as a propeller moves water. But they actually spin counter-clockwise like a boat propeller spinning in reverse? Very counter intuitive, but apparently good aerodynamics? However, what I really wanted to mention, is that it looks like you’ve partly attached your fans to the lower edge of the upper vent cover bezel. This makes me wonder if your’e aware of insect screens? Oliver recommended them to us, but your fan mounting screws would probably interfere with the screens tight fit. That’s why I mounted my fans to the back wall with PEX pipe standoffs. FYI. screens are available at etrailer for the Upper and Lower vents, and for the furnace exhaust, and I think they are worthy upgrades. Cheers! Geoff

@Ronbrink Yes! That's exactly what I said! However, the Beech Lane fans blow inward the with label on the outside (at least the ones I bought). This would be the right direction if mounted in the bottom vent as intended by design, but the wrong direction if mounted in the top vent. Cheers! Geoff

@jd1923 and @Ronbrink you guys did a good job too! I will check out that evaporator fan, I could run it from the same switch perhaps. It's hard to tell from your photos, and forgive me if I'm mistaken, but it looks like your Beech Lane fans are blowing air in the wrong direction! They are designed to be mounted in the lower vent to push air out of the top vent. When installed in the top vent, they push air out of the bottom vent, which is working against the Norcold fan and natural convection. Try flipping the fans around in their mounting brackets so the label is in the back, and they will work much better! Cheers! Geoff

During the hot weather this summer, our Norcold refrigerator was also struggling to keep cold while on propane. The fridge fan could not remove enough heat for it to work properly, so it was time to install more cooling fans! I ordered the $75 Beech Lane fans based on the positive reviews, but there was no way they would fit in my Norcold’s lower vent area as intended. They could fit in the upper vent with modified mounting brackets and reversed air flow, but why pay for something that didn’t fit as designed. In addition to fitment issues, I didn’t like the control box being mounted outside behind the vent cover where the blue LEDs can be seen glowing. I wanted the ability to turn the fans off, but the control box didn’t remember the last setting when the power is switched off, and I didn’t want to be opening the vent cover to reset it. These are multi speed fans with 3 wires so switching the fan wire wasn’t a good option either. I returned the Beech Lane fans and bought 2 similar (water resistant) fans and a Normally Open 500c (1220f) thermo switch for lots cheaper. I made a rectangular frame of 1/2” aluminum angle bar for the fans, and installed them in the upper vent. Because the upper vent has an angled back, I used long deck screws with short PEX pipe standoffs on the bottom screws to keep the fans mounted vertically. The Beech Lane fans would have to be mounted the same way if I had kept them. The fans are powered from a new switch in the master panel and it’s in series with the thermo switch so they will only work when the switch is on, and the temperature is above 1220. I used a laser thermometer on the condenser fins when the refrigerator was operating on propane. The temperatures were significantly higher on the right side above the flame chamber, and they got progressively cooler towards the left side. So I hung the temperature switch between the condenser fins just right of center. It can easily be moved left to cooler fins if the fans are running too often. I installed a terminal block as a centralized connection point for all the wires, but they could be spliced together in any manner of ways. “Y” spade adapters worked well to connect to the refrigerators existing dc power terminal via a 5 amp fuse. The fans use less than 1 amp combined. The microwave was removed (six screws) to get wires up to the new switch on the switch panel. The tension jack to hold the microwave in place has to be loosened too, it’s accessed through the round marine hatch behind the switches. Just takes a couple of minutes to take it out. We have been testing the fans in 100 degree weather for the past week, and they've been working great! I hope someone finds this useful! Cheers! Geoff

Tim, The "blown fuse" LED indicators in the Oliver's dc panel will create a voltage even with the fuse pulled. This is mere milliamps, not a hazard, but a multi meter will pick it up. Cheers! Geoff

Wiring used by manufactures for trailer brakes may seem ugly or brittle, but it has properties and insulation appropriate for the application and harsh environment where it can exposed to water, oil, chemicals, constant vibration, and abrasion. Please use caution using extension cords for brake wiring because they could have inferior wire that looks good, but with insulation that could deteriorate and fail over time. Trailer brake wire is readily available for this purpose, and it's a better and proven choice. Cheers! Geoff

Hey Bob, If you’re pressed for time and it doesn’t re-set, then you might be better off trying to fix it yourself because Truma service could be inconvienient, untimely and expensive. I’d check for a degraded pump, or a debris jam thats causing excessive current draw as the error code indicates. The year warranty is probably expired so it could be worth a try. If the WH operates at all before the error code shuts it down, then listen for unusual pump noise and/or measure the current draw. It normally runs just long enough to fill the reserve tank with hot water, and a DC clamp-on amp probe can be used to measure the current from the front panel. AC/DC amp probes are readily available and you can use the wiring schematic in the Truma Manuel to identify the pump’s wires where they enter the control board in front. Just separate one of the pump wires from the bundle, and clamp the probe over it. The pump is rated to draw less than 2.5 amps when pumping. If the error code is preventing it from running, then you'll have to remove the WH and take the pump out for testing. It takes a little time but it’s not difficult. Drain it through the front flip down drain before disconnecting the plumbing. Disconnect the propane line and unplug the control wire from inside the unit, cut the DC power at the splice in the back by the water connections. Carefully use a heat gun, spray solvent such as Goo Be Gone, and plastic putty knife to break the outside seal, and have some butyl tape and outdoor caulking on hand to reinstall it. Once out, connect a standard 1/2" NPT residential faucet hose to the pump's intake, prime it, and put the other end in a bucket of water. Connect it to a 12V battery with jumper cables and use stiff wire or paper clips to connect to the pumps plug. It should pump with good pressure and <2.5 amps. If the pump is okay, then unfortunately you're back to control board issues and probably going to the Truma dealer for diagnostics. But you will only be out of your own time for trying. The pumps are pricey at around $250 when I last checked. Only buy one from a reputable dealer because I saw a fake site advertising them for $55. I hope this helps! Good luck! Geoff

JD, This is unfortunately one of the drawbacks to the Victron inverters, but supposedly you can switch it to charger only mode to allow shore-power pass-through with the inverter off, with less standby power used. Bit of a pain though! However, a clever and handy guy such as yourself could install an external by-pass switch that would be easier than the App. Victron makes an inexpensive 30 amp beauty for switching between a generator and shore-power. I've seen them for $45. This can be wired so that you can switch the inverter off and still have shore-power. It's a great solution that might get you some extra sleep! 🥱 Cheers! Geoff

Bob, I was using the specs of my Xantrex Freedom 2000 model to make a point about power consumption in standby mode, without any AC load. Different models will vary. The newer Xantrex models have a "No-load detection" feature that reduces the standby current by 25%, or to about 60 AH. This is similar to the Victron's power saving modes. Be sure to check your settings, because this feature is usually turned off in the default settings. However, I don't know the minimum current for the No-load detection off-hand, so it's possible that ghost loads like the microwave LED clock could defeat its value. And your assumption is right, this applies to any type of batteries. Hope that helps! Cheers! Geoff

David that's very cool and clever! Sounds like you know the maker! Do you think you could get the slicer file from him, or have him put it on Thingiverse? Is it made from PLA filament? BTW, I never mentioned it, but the rubber weather cap that comes with the Rj45 socket can be used under Furrion cap. Mine has disappeared though! Thanks, Geoff

While preparing for an upcoming trip, where I’ll probably need to run a generator for AC, I decided to utilize some unused space in the dog house to store my RotoPax 2 gallon gas can. I used to carry it in the tongue tray with the generator, but now I’ll always carry it for emergency fuel. I made a rectangular box that's sized so there is just enough friction to hold the gas can snugly in place without needing a strap, and narrow enough to fit between the propane tanks and the front of the doghouse. The tank can’t come out anyway because of the doghouse cover. I measured the can after leaving it in the sun for a while to account for any expansion. The fuel can holder is made from 1/2” void free plywood (baltic birch), and it’s put together with glue and screws. It was rattle can painted with primer and plenty of white gloss, then attached to the frame with self drilling 1/4” screws, like the ones holding the propane tank tray. It can be locked through the handle if desired. The RotoPax gas cans were originally made for off-roaders, and they are pricey at around $85 each. But they are practically indestructible, and they come in different colors for diesel or water. I’ve had mine for around 7 years and it’s never leaked a drop. There are knock-offs available on AZ for about half the price, but I can't vouch for their quality. From the plywood scraps, I also made a little box for the luggage scale that I use for weighing the propane tanks. It was made in the same way with magnets to hold the hinged lid closed. It was mounted in the doghouse in front of the propane tanks. Hope someone finds this useful. Cheers! Geoff

Nice work Don, very creative and well documented! Being such a handy guy, you might also like my post "Turning on the rear camera automatically." It sure beats always having to remember to flip the camera switch on and off every time. Cheers! Geoff

Just an FYI. If the digital rear view fails, it still acts like a normal mirror. It has to, because the camera doesn't work well in the dark.

A friend of ours rented a private trailer this summer, but he had not slid his receiver hitch fully in, and the retainer pin missed the hole in the shank. A dip in the road caused the receiver to slide out, and both safety chains broke. The violent snap caused the propane to break free and hit the windshield of a following car, causing a minor eye injury from glass particles. He said the chains were "hefty." It would be hard to determine the force put on those safety chains, but it must have been considerable! Just sayin, a chain is only as strong as the weakest link!

Good on you for your perseverance and skill at getting the Norcold fixed! Thanks for providing part numbers and giving hope that problems with these, now obsolete, refrigerators can still be repaired. I think it would be great if you explained how to remove the front panel right here on the forum. I'm sure others would benefit . . if not now, then later. Congrats! Geoff

Those are parking places to keep dirt and water out of the cables. One is for the DC to DC charger cable made by Trailer Vision. They also make the plug covers and receptacles for Anderson connectors. The other one is for the 7-pin cable (AP Products Plug Guard.) Cheers! Geoff

Camera is through bolted with nylock nuts as to not to chip the fiberglass, like happens with sheet metal screws. The very tip of a step drill works well for making holes in the fiberglass because it doesn't grab and chip like a twist drill. Cheers! Geoff

Thanks JD. Yes, if you disconnect the grounds the LEDs won’t work, but switches will still work. Also, if you want the blue lights, then you can replace your switches with LED types available at AZ. i like the blue lights, just not so bright! Geoff

I like our 2022 RAM 2500 gasser a lot! Some of the many notable features that we like include Apple Car Play. It always synchronizes seamlessly, without the frustration we've had with other cars including our old 2016 Ram. We frequently use it to display full screen Google maps from the phone, and we can toggle back and forth to the RAM GPS which offers nice features too, like a side bar that shows upcoming rest stops, gas stations, etc.. My absolute favorite feature is the digital rear view mirror camera option. It's a high resolution and wide angle view that is way better than the standard mirror. Best of all, it has an auxiliary camera for mounting on a trailer, and the resolution is just as good. I think it's a fantastic towing safety feature, where you have an excellent wide angle view of directly behind and side lanes where there is normally blind spots. There is an outlet in the rear bumper for the trailer camera, and a cord garage for the trailer during storage. My camera is mounted on the spare tire cover. It also has a 5-camera outlet for a trailer surround and interior views, but we don't use those. Other features I like, are the side mirror sensors that warn of vehicles in side lanes. This can be adjusted for your trailer length. The self adjusting steering aggressiveness for highway and town is just right, and the lane departure steering correction is very suttle, even better than our Tesla that can startle you with aggressive corrections. I'm sure that other trucks have similar features, but I also have a personal preference for the RAM dashboard layout and controls. That my two cents worth! Cheers, Geoff
