Wonder / Re: Ok to use Wonder in cooler temps?
Last post by alaskajen -
Go for it!

We have a 2022 Wonder RTB AWD with 4 solar panels and dual lithium options. We've used it a bunch in winter, below freezing temps but not below 0°F yet. We live in Northern VA but travel all over. And I'm originally from Alaska (born and raised) ...

RTB has fresh water tank "inside" so that's not an issue as long as you have heat inside. What you need to be concerned with are exterior plumbing lines, any tanks not "inside", and gate valves. Also, we were told before we purchased by someone at LTV to NOT get macerator pump option for dumping if we were planning to use in cold weather. So we didn't. I don't know all details but for us it's not an issue as we don't have.

Lines are small/thin and will freeze easily. Stuff in tanks will freeze eventually but shouldn't break anything as long as freezing contents have room to expand into (i.e., tank's not full). Obviously dumping frozen tanks is impossible. And frozen gate valves make dumping impossible until you thaw, too.

Quick and easy method to overcome all of that is to winterize RV when it starts to get cold. Then we DON'T use fresh or gray tanks at all. We use toilet but flush with RV antifreeze for black. This hasn't given us any problems. Just dump black tank as needed, flush black tank with water if you can manage, blow out flush line with air (like manual says), and rewinterize toilet by dumping some antifreeze down and flushing a few times. Works great!

Just make sure you know which antifreeze you're using -- concentrated or diluted. If concentrated, you'll have to mix with water but keep in mind urine and poo are liquid too. If diluted, you should use a bit more to compensate for urine and poo as a freezable liquid. Things might get slushy but shouldn't freeze totally.

Ultimately we put heat tape/pads on all our external lines, grey and black tank, gate valves, and in our service bay. It's quite a luxury! But we really only use this if were caught off guard with weather or haven't prepared/winterized. Now I know I have a backup plan that will keep things moving and unbroken!

If you have Lithium, don't forget to turn your battery heat switch on and leave on. It is temp regulated and only comes on and goes off when it needs to.

As for staying warm, we have Reflectix insulation on cab windows inside. Outside, we have an insulated cover for windshield and side windows (one piece, wraps around).

Also inside we have foam insulation cut and inserted to fit in all coach windows and skylights, then covered with Reflectix insulation (hook and loop tape; shiny side facing IN to coach to keep heat in).

We bought some insulated vent fan covers (magnetic; quick install).

We also bought a cheap commercial sized/grade carpet with rubber backing that we cut to fit our floorplan's unique shape. This keeps feet warm and heat in, too.

And we bring back up heaters like propane fueled Mr. Heater and an electric space heater that do a great job if furnace were to fail or we ran out of propane (when temp are hovering around freezing, we use maybe 2% of propane a night).

We also bought a large insulated cargo cover blanket (like truckers use) to clamp between cab and coach for insulation. This makes a HUGE difference! I wish someone would make a custom version you can just buy and use those snap grommets to install!!!

And we're wearing plenty of layers and using extra blankets, too.

It's very doable for moderately cold temps. But I don't think I'd want to try at -20°F ...

Wonder / How to Disconnect Lithium Batteries, Zamp Solar Controller
Last post by alaskajen -
We have 2022 Wonder RTB with dual lithium batteries and 4 solar panels options added at time of purchase. We've had for about a year and a half now. But we never needed to store batteries during winter before because of a lot of use. We're not traveling this winter. So new this year, I need to know how to properly disconnect the lithium batteries -- what precautions do I need take, what is process. And I need to know if there's something I'm supposed to do with/for the solar panels or Zamp controller box as part of this process.

Sorry if this has already been covered here; couldn't seem to find. Finding instructions in manual to be lacking/unclear. And looking online is yielding a LOT of mixed/conflicting results ...

I know what to do with battery to maintain/preserve it over winter once it's disconnected. I just need to know how to disconnect from coach so it's not getting any power. And to make sure Zamp controller doesn't get messed up in process because of solar option.

Any help anyone can provide would be VERY appreciated!!!

Wonder / Extra Brake and Reverse Lights on Rear?
Last post by alaskajen -
We have a 2022 Wonder RTB. Finding the exterior lighting to be a bit dim. Specifically the headlight low and high beams and the reverse lights. Also concerned the brake lights are spaced so far apart people may not see them as quickly if they're close. We've modified to get some lights on rear sides and front (separate switches run to their own power). But has anyone tried adding additional brake and/or reverse light(s) on rear of Wonder?

I know how to wire things on separate power and switch. But want to tap in so the lights come on when brakes are applied or vehicle in R. On the internet, I'm reading about issues tapping into lights directly (something about blowing up Ford's CAN bus and/or there not being enough power for aux lighting coming off of existing?). And using trailer 7-pin to 4-pin adapter to use strip lighting is yielding all sorts of Ford faults and lights don't work as they should (and it has your Ford in "trailer" mode the entire time).

Anyone have experience? Ideas?

Unity / 2021 Unity MB Window seals
Last post by Darryl Miller -
Are any of you having problems with your window seals tearing?  Looks like they shrunk back and tore in every corner.  This happened in every window and this is a 2021 unity MB.  LTV said passed warranty and so did Lippert (manufactured the windows).  Can't believe this is not a defective material issue across the board for several units.

LTV Discussion / Re: Starlink installation
Last post by Christopher -
Update. I mounted the Starlink router in the rear bin, and added a separate inverter (wired to the generator dc circuit). A lead from the invertor was pushed through the wall to the bathroom for a remote switch and monitor. This means you don’t have to go outside to switch off the Starlink when not in use. The Starlink antenna cable is run through a rubber grommet in the floor. The antenna can then be ground mounted on the standard Starlink holder, or it can be mounted on the mast according to site conditions.
