Having just purchased a low miles 2022 Wonder model 24FTB, we have some additional questions for the group. Hoping some of you have experience with these things: 1. If there is a nice set of rubber floor mats we could purchase for the driver and passenger areas, does anyone know who makes them and where we could find them? 2. If we were to decide to upgrade from the two OEM AGM coach batteries to Lithium, is that a good idea, and if so, which battery(s) do you recommend? (I see that LTV has started supplying new Unity and Wonder vans with two Dragonfly 100Ah batteries; but I also see that the guy on Pagosa Supply recommends a single Lithionics 12v 320Ah battery). 3. If we were to go up to 320Ah of Li battery power, should we also install a new 3000 watt inverter? If so, which one is recommended? And what else would we need to install (such as a new battery monitor)? Given that this camper came with a generator, I am not sure we would need to do all this -- even though we have done something similar with the 2019 Ford Transit camper conversion we had done for our daughter and grandaughter here in San Diego -- thereby making it an all-electric camper. Your thoughts? 4. Along the same lines, if we do upgrade and increase the battery power as per the above, should we also add at least 200 more watts of solar panels to the existing 200 watts of solar panels that the unit was equipped with from the factory? If so, which panels do you recocmmend? (We did exactly this on our Airstream trailer). 5. Has anyone found a freestanding shelving unit that fits within the large outdoor storage bin that the FTB has on the driver's side? 6. Having had good experience with a 12v compressor fridge in our current travel trailer (this van will replace our 2021 Airstream Globetrotter 23FB twin), does anyone recommend replacing the OEM Dometic RMD 10 with a compressor fridge? If so, which one is recommended, and does it fit within the existing cabinet?
Please note that we are both in our late 70s, so probably no longer up to doing much of the above work ourselves.
Thanks in advance folks for any recommendations you may have.

Thanks. Unfortunately the manual is in the unit, which is being stored at the dealer's lot in Vegas until we can pick it up on our way back to Denver around May 1st. We want to purcahse the battery(s) and bring them with us for installation at the sealer's lot.

We just purchased a nice, low miles, 2022 Wonder 24 FTB from Van Life in Las Vegas. We had ordered a new 24RTB a couple of years ago through Van Life CO Springs, but cancelled it after the price increased to over US$200k. But when we checked out this one in Vegas, its chassis battery was dead until they jumped it for us.
So we want to replace that battery, which we know from replacing the battery on our daughter's 2019 Ford Transit van conversion here in San Diego just last week, is located under the driver's seat.
Does anyone know what battery this '22 Wonder 24FTB takes? Or is it two batteries in this model? Please advise. Thanks,
Tom
PS: We have several other questions for the panel, but will submit those in another posting.

I had repairs to the Onan LP generator which ended up being a leaking propane line and the circuit board was arching (not so very far from the propane leak, however I'm still alive the Unity did not explode). Now the generator purrs nicely, starts up fine, but two issues: (1) it works fine as long as the circuit breaker is off, which isn't too useful; (2) when the shore power is detached, the generator dies after 5 seconds, and a dead battery error shows up on the monitor. House batteries are OK on testing, charged. Resetting the generator a couple times did not resolve or change the issue.
Anyone have an idea where the disconnect, short or whatever that would give one or both of these issues. Would like to understand it a bit better before going back to the repair shop and having them dither about at $195/hour.

Indeed, it does, allowing the generator and shore power to charge the chassis and the chassis alternator to power the house along with the house batteries. It the isolator switch is under the front passenger seat (not the most difficult to pull and put back). I unfortunately changed it out when that was not the issue for the two batteries communicating. The issue I had with the used Unity was a blown 200 amp fuse adjacent to the chassis battery under the driver's side floorboard. So, if you aren't seeing a connection between the two batteries, the fuse is a $6 fix (even ordering 2 fuses), as opposed to the few hundred dollars and time to remove the passenger seat. Glad to go through the whole litany if you're curious or in need. Having the two batteries communicating has made life in the Unity so much easier, that is until the next electrical issue came up.

I just took delivery on a new 2025 60th Anniversary Edition Unity MLB last month. I have found that when it is raining any significant amount at all, the rearview mirror camera that is mounted up high at the roofline on the back of the rig becomes totally obscured by rainwater running off the roof while driving, making it useless. It is totally blurred out by the rushing water.
Does anyone know of a solution to this? Like a moulding to surround the camera on top and the sides that peaks in the middle, channeling the rainwater away from the camera? I'd like something that is purpose-made for this and doesn't look jury-rigged. Thanks.

Does the Unity LTV have a chassis isolator switch which allows the chassis alternator to recharge the house batteries when the engine is running? If so, what year models includes this mechanism? If not, would an isolator switch be recommended without upgrading the alternator?
Last post by JoeElegar - If you're looking for a front windshield cover for your 2019 Wonder that also protects the wiper gully from leaves and pine needles, you're on the right track. While Coverking offers a good option, other companies like WeatherTech and ADCO also provide high-quality covers designed to fit various vehicle models, including RVs. These covers not only protect your windshield but also help prevent debris buildup in the gully. Regular maintenance and using a cover can also extend the life of your windshield, reducing the need for premature windshield replacement.
