I would choose #3 as long as there's nothing right up against the furnace exhaust. No guarantee the forecast is right. Miscalculated once with a different trailer and ended up replacing a split fitting on my water heater.

For anyone else with a 2022 that got tires with balance beads in them: We installed the filtered valve cores Oliver provided and run the tires with external tire pressure sensors. This year, when I removed the sensors for the winter, I found that 3 of the valve cores had loosened on their own and were leaking, while the 4th one failed altogether. Here are the replacements: https://a.co/d/0dIxCKgF I recommend you keep some on hand along with a valve core replacement tool.

Reading through the Lithionics document again, it seems like those of us with internal BMS are supposed to run the battery down to 0% SOC to trigger the calibration. However, those with the V9 external BMS can run down to 10% to achieve the same thing. Does everyone else read it that way? That does make me uncomfortable and I would definitely like to have the new firmware available for my internal BMS batteries.

It is what was recommended by Lithionics: What is SOC Drift and how to avoid it? : Lithionics https://share.google/oh46MD3Ckxst17rsU I was aware that Lithionics had updated firmware that added that function to their *external* BMS batteries but haven't heard about it for the internal BMS batteries yet. "Older versions of Lithionics Batteries do not currently have the automated Usable Ah calibration feature but will receive similar firmware update in the future to enable it." I have firmware version 2.1.11

It's possible your SOC is out of calibration. Have you ever run the batteries all the way down to shutoff then recharged them to full?

According to the product page, Supertech RV Antifreeze contains Glycerin (Glycerol): An additive that helps lubricate and protect plumbing seals. Also Propylene Glycol: A non-toxic (to humans when used as directed) organic compound that lowers the freezing point. So, it's not all ethanol. Never had an issue ourselves in the past 27 years. On the other hand, we have had a CO/gas detector become overly sensitive and need to be replaced.

I wonder if this is what happened in @Rivernerd's case, where the fresh tank pressurized? Same with our 2022.

Most 30-40 degree nights when using the furnace we find that just cracking the Maxxair vent a tiny bit using the hand knob is sufficient venting to prevent humidity/condensation buildup. We never open it all the way with the furnace on.

The screen should be at the end of the tube, not part way up. Plenty of room for a wasp nest below that screen.

With a tandem axle trailer and a heavy truck you can have a catastrophic trailer tire failure and not even know it. You won't feel it. With the TPMS you know right away and can start reacting, minimizing damage to your rim and trailer and reducing overloading of the remaining tire on that side. That's what happened to us. Our TPMS went off and we got away with only a broken mud flap and cosmetic damage because we stopped with most of the tire still on the rim. You could also have a fast leak from road debris. It could go flat without you feeling it, then chew itself to bits on the rim before you knew you had a problem. Our TPMS also alerted us to a catastrophic trailer brake failure. One wheel started running much hotter than normal. We pulled over and heard noise from that wheel. Turned out the brake assembly had come apart inside the drum. So, yes, I consider TPMS a crucial safety feature.

Having experienced a catastrophic blowout on a different trailer, I don't mess around with tires. Tire pressure monitor and replace trailer tires every 5 years, regardless of mileage. The problem with trailer tires is the lack of use. Flexing the rubber is actually good for it, so when a trailer sits, the rubber deteriorates faster. Worse, the problem can be on the inside of the tire, even if the outside looks fine. It's shocking how much damage a tire carcass can do to a trailer when it sheds at 65 MPH.

I understand the flexible connection because the shower pan actually flexes a little when you stand near the drain. But this was sloppy work at the factory. Can't say I'm surprised because we've had several issues with sloppy work in our 2022 as well. It's also disappointing to hear that they denied your warranty claim because you couldn't get it to them within the warranty period, even though you identified the issue within the warranty period. Hope you can resolve it without too much trouble.

That begs a question. What's the internal diameter of the overflow tube? If it's equal to, or larger than, the shoreline hose and the plumbing leading to the tank, wouldn't they have the same flow rate?

@Skynyrd, there are several threads discussing this in the forum. Google "Oliver trailers forum Winter camping." There are weak spots in the plumbing that may or may not have been addressed with some of the changes in the more recent model years. Like @DanielBoondock says, any camper can be a winter camper if you want it to. I've seen Airstreams being used all winter here in CT. Full hookups, belly skirts, and lots and lots of propane. Not my cup of tea, though, and we also consider our Oliver a 3-season camper.

Again, wow! I wonder what went wrong? We've filled that way dozens of times. Of course, 35 psi of non-compressible water can still do a lot of damage if it has nowhere to go, but you said it was venting out the overflow tube. Will be interested to hear if your tube is kinked or blocked somehow. Enjoy the rest of your, hopefully uneventful, trip.

Wow. Sorry you went through that! Hope everything's ok. Unfortunately for us, going by the tank monitor is ineffective. It reads full long before the tank is actually full. We will use a pressure regulator when filling and monitor closely, though. Thanks for the warning.

Bug and Tar Remover, then wash and re-wax.

We have a 2022 and the same situation with the carriage bolt holes. One was so large the bolt would turn in the hole and was never fully tightened to spec at the factory. Had that bracket replaced at the factory under warranty.

Updating the original crack situation: We did end up taking the trailer back to TN for repair of the fiberglass under warranty.

Not sure what a screen way up inside the pipe accomplishes. There's already a valve to keep critters from reaching the tank. A screen right at the outlet would make more sense, to keep wasps, etc. out of the tube.

Hi. Read through this forum. Use Google search: "Oliver trailers forum <insert your question here>." Tons of good information available.

We have a crew cab long bed. The long bed is good for storage, especially if you have a large Clam screen room. The downside is maneuverability. Our truck and trailer combined are about 45' long. Makes it harder to back into some campsites with narrow roads and trees.

Totally agree with Bill. Your readings seem high, but we always have to raise the nose when dumping. If we don't, we often have 6-12% left in the tanks (according to our monitors).

As mentioned earlier, we've had 2 RV Lock keyless locks on our 2022. Both failed, one possibly due to water intrusion because Oliver cut the latch hole in the door too big, leaving a gap next to the exterior portion of the lock where water could get in. OTT sent us a replacement and I caulked around it. Even so, the replacement failed after 3 years for unknown reasons, so we gave up on RV Locks. We were just at the Hershey RV Show and met a rep from Global Products Group who showed us their Ultra ES Pro lock. The first thing I noticed was that it was very substantial, all metal construction. It also uses a different handle configuration inside and out. We talked him down to a price we could accept and bought one. I just installed it with no issues. The first thing I noticed was that the exterior portion was larger than the RV Lock, so it covered the gap left in the door by OTT nicely. It also included a large neoprene gasket, which was nice. Installation was easy and it functions well. One interesting note: there is no separate deadbolt. The deadbolt function simply locks the single bolt in place, rather than extending a second bolt. It would still stop someone from jimmying it open, though. The second thing I noticed is significant for us. Even with the striker plate all the way out, our door never latched easily. We had to really slam it to get the RV Lock to engage (perhaps the cause of the demise of lock #2). This latch closes cleanly and easily using the original striker plate. Our sleeping neighbors will be much happier. OTOH, the Bluetooth app for the lock seems glitchy. It has trouble staying paired to my Pixel phone. Not a huge deal for me, but maybe for someone else. Time will tell if this lock holds up. Will update here if things change. Here's an Amazon link: https://a.co/d/0bzR8SDZ

Yep!
