Scary scenario. From what I gather, the man reached under his Anderson leveler to pull it out and the truck/trailer rolled a bit, probably from the play present with the parking pins in an automatic transmission (I know my truck can move an inch or two before the parking pins engage.) This is why you never put your fingers underneath anything that could take a load (tires, jacks, cribbing, etc.). Also why I always walk back to the cab of my truck to verify it's in Park and the brake is set before I lift the trailer off the ball or pull any chocks. In addition, I double check the chocks and leave the safety chains on when I lift the trailer off the ball. I did have a truck/trailer combination start to roll on me once because I forgot to put it in Park. We also once had a "toad" car behind a neighbor's motorhome roll across the road and hit our trailer when they forgot to put it in park before unhitching. Large vehicles moving unexpectedly is very scary. https://blog.campingworld.com/lifestyle-activities/you-need-to-hear-this-story-before-you-go-boondocking-all-alone/

Welcome.

Our other trailers all had separate breakers for the fridge and water heater. This 20 amp circuit was a surprise.

Here's the link to our thread about this failure: https://olivertraveltrailers.com/forums/topic/7188-120v-wiring-failure-good-news-on-fridge-outlet/

This happened to us. In our 2022, a single 20 amp breaker runs both the fridge and the Suburban water heater. There was a junction box on the side of the water heater (under the bed) and I found one of the wire connectors inside melted, leaving the circuit to the fridge dead. It looked like the connector wiggled loose and overheated. After replacing the connector, I added some zip ties to minimize movement of the wiring during travel.

Another thing to try: In our previous SOB trailers I could often remove the yellowing on white plastic parts with black steak remover spray. Might be worth a try first.

@NomadLife, if all the above do not work (the valve under the dinette is definitely open but the tank still doesn't drain) you may have a "black pyramid." This is when solid wastes block the outflow pipe. The solution is usually unpleasant: running a snake up the drain to dislodge the blockage, thus releasing all that black tank goodness back down the pipe at you. 🤮 For reference, to prevent black pyramids always include plenty of water when you flush solids (a full bowl), use RV toilet paper sparingly, no wipes/feminine products in the toilet, only dump when the tank is at least 2/3 full, and never leave the black tank valve open when at a campsite with sewer. You want lots of fluid to move the solids down the pipe. Otherwise, they can accumulate in the tank and solidify.

Looks like a great trip. Curious: where do you put the litter box?

If you're sure it's not sewer or propane, another suspect could be the gray tank vent. Gray tanks can smell as bad as black, believe it or not. Your vent stack could be disconnected somewhere. Maybe someone else can describe the routing of the vent pipe.

I saw some strange behavior with the Lithionics-reported SOC while our trailer was stored indoors in a similar situation, with some trickle from the solar due to interior lights in the garage, etc. The two batteries were "discharging" at very different rates based on the reported SOC. Importantly , the actual voltages were the same. I tried discharging them, then recharging to full to reset the SOC calibration with no luck. Then I tried turning solar off with no change. However, when I pulled the trailer out of the garage and got regular solar running again everything went back to normal. I have no reasonable explanation, but I don't think you can trust the SOC reading too much when it's stored this way. Voltage is a better indicator. @Dave and Kimberly, how do the voltages in this chart for 12v LifePo4 batteries compare to your batteries' voltages and the SOC being reported?

To answer the OP's question, no comparison. Oliver uses much better materials in their construction. Aluminum frame vs steel, fiberglass walls vs aluminum. Double pane windows. It goes on from there.

I wonder if the safety override still works for those of us with lithium batteries? The 12V feed from the truck isn't connected to the batteries. Is it still connected to the awning? Will have to try it sometime.

We had OTT install the RV Lock on Eggcelsior. It's ok, but the first one failed after water got into it due to an install error by OTT. Before our Oliver we had this lock on two trailers: LATCH.IT Keyless Door Lock for RV Sealed Electricals Unlike Competitors! | Fits 2.75"x3.75" Lock Hole https://a.co/d/1lhYkU0 I think the LATCH.IT lock was superior to the RV Lock installed by Oliver, with a better build quality. Both are easy installs.

Congratulations. 30 is a big one!

Natural Bridge, VA might be a nice stop on your way north, too.

The neutral bonding plug goes in one of the 15A standard "household" outlets on your generator and connects the ground lead (the round third prong on the plug) to the neutral lead (one of the flat prongs). Without going into details, this is the setup the EMS expects to see, but most portable generators are not set up that way. Hence the plug.

12.1 volts is just about 50% SOC for your AGM batteries (wired in series to produce 12 volts). You generally don't want to discharge them below 50%. That's why the inverter is set to cut off at 12.1 volts. "Try to keep your max discharge level to 50% – this is 12.1v on AGM batteries – as our cycle life data is based on a 50% discharge level. You can technically take AGM batteries lower than that, but the cycle life will reduce accordingly." Source: https://www.alpha-batteries.co.uk/blog/a-detailed-guide-to-agm-batteries/#:~:text=Try to keep your max,will increase the cycle life. I've read that you can technically discharge AGM batteries all the way down to 20%, but you'll greatly reduce their lifespan.

As @jd1923 mentioned, there are charger settings that need to be changed on your Xantrex for lithium batteries. OTT could provide those for you. You might need to change the cabling to fit the new battery terminal locations. Our Lithionics report their SOC through a Bluetooth app, so we don't have a separate shunt, but they are expensive. As for running the A/C, we have the 3000W inverter and can do that for an hour or so and recover the charge the next day if it's sunny.

This is good. I wonder if OTT will allow us to go to a nearby non-Oliver RV tech if we don't have an OTT dealer nearby?

The 1304 number came from NHTSA site as the "potential number of units affected," not the number of dealers. Since our 2022 is #1150, and some others were delivered with 2 ⁵/¹⁶" couplers, it seems reasonable that 1304 is the number of LE2s manufactured with 2" Bulldog hitches between 2009 and 2024. I suspect(?) they want them all checked. The form posted by @Geronimo John seems to indicate they want the hitch inspected by a "service facility." I know ours is stamped 7000#. Next time I have it in the shop for something else, I'll have them sign the certificate, too. The recall won't matter unless I want to sell it later.

Since we're taking about refrigerators... Your trailer is level, correct? You shouldn't run an absorption fridge with the trailer more than 3 degrees off level front to back or more then 6 degrees off level side to side.

"Potential Number of Units Affected 1,304" So, are they recalling all LE2s for inspection?

Looks like this is related to the earlier report of a mislabeled Bulldog coupler failing: https://www.nhtsa.gov/recalls?nhtsaId=24V322000 Good that OTT is following through with this.

That seems like a lot to me. Do you have the 20 or 30 gallon propane tanks? We have 30 gallon tanks and usually go through 1 or 2 tanks a year. I would expect a tank feeding only the fridge to last weeks. Are you using other propane devices, too, like the stove or furnace? If it's only the fridge, could there be a propane leak somewhere? You can check the connections/fittings by spraying a little soapy water on them and looking for bubbles. Or, could your tank sensor be wrong? When you get it refilled, see how much propane it takes. It usually takes about 6-7 gallons to refill a 30 gallon tank. As for fridge operation without shore power, propane is the most efficient, DC is a big power consumer.

On the I-81 side, Jim Thorpe, PA is nice. We were there recently and posted some info/photos on our blog. Also, maybe run part of the Blue Ridge Parkway/Skyline Drive? Along the east coast there's Ocean City, MD and Assateague Island. Gets you off I-95, which is not a fun road.
