.

If you want to hear first hand experience on the RT lithium system,
you need to join the Facebook group called:

Roadtrek & Hymer Owners Group


There are at least a couple of active members who have CS Adventurous XL with 1600AH ecotreks.

This will allow you to accomplish two things: (1) You won’t be overpaying for Roadtrek’s system and (2) you can find a new or used B at a much better price.

If the federal solar tax credit is still in effect (it was last year), you’ll even get a 30% tax credit against the cost of your upgrades (just remember to have them to install at least one solar panel). If the tax cut has expired, adding solar might not make sense. This FitRV post will help you understand the pros and cons of solar.

Since you live in WA, you could drive down to Oregon, to have AM Solar put in lithium batteries, inverter/charger, and a Victron Energy Color Control GX panel so you can monitor the state of your power down to the watt.

A system like this will almost be like like being plugged in at home. You can run your AC + microwave simultaneously, you’ll be able to monitor see how much power is coming in (solar, generator, alternator) and out (both 12 volt and 110) from your batteries. If you have an internet connection in the RV, you can even monitor the state of your batteries over the internet.

Here’s a very of the panel. I have one and I really like it a lot.

If you buy a new/used class B with the traditional generator setup, you can upgrade in stages. Start with the lithium, inverter/charger + panel, and solar (if it makes sense). And then use the generator (or idle the engine) once every few days as needed. Eventually you can remove the Onan generator and install a second alternator if you decide it makes sense.
Thanks very much for that info. I'm looking forward to contacdting those companies to see if there is a better way to do this. Much appreciated!

Wondering how easy it is to find an RV with all electric appliances for this conversion and wondering if this system can be powered by solar and underhood generator and also shorepower? I'll give the company a call and ask them.

I do not have ecotrek-however i monitor the forum that discussess this on facebook many days and have since ecotreks were intoduced.

I have a zion with tppl agm and am quite satisfied with it. i did not over expect.

My opinion for the system you want is go with ARV.

they are far more likely to give you a satisfactory system

ARV builds amazing RVs but with an amazing price to match. If you want a high end custom layout, ARV is the only option. If you just want a fancy lithium system, there are lots of options that don't involve plunking down 300k.

Who specifically?
AM Solar located out in Oregon. They've been RV solar pioneers for a long time now although the ownership changed hands in the last couple of years. They primarily focus on larger rigs and they don't fabricate below-floor battery storage like ARV, but they install reliable, powerful systems. I expect your local solar power installer could do a lot of the troubleshooting since the same components are used for home and yacht setups.

Now I didn't say anything about cheap. AM Solar only uses high end components and skilled labor isn't cheap, but you get what you pay for.

-Automatic Cold Temperature Disconnect
-Complete Color System Monitor
-WiFi Connection for Remote Trouble Shooting
-Automatic Reset on Battery Management
-Compatible with multiple charging sources including: Solar, Alternator, Generator & Grid


Throw in a 3k Victron inverter/charger ($2,150 last summer) + labor and you have an amazing system. They don't install second alternators but they'll hook it up to the system.

Second alternators for Sprinters and Promasters aren't cheap, so WingedRyno probably would be better off making due with the stock generator and single alternator until they're sure they want to jettison the Onan for a second alternator.

actually the best bet if your going this way-have sportsmobile build everything else and leave areas availlable for am solars stuff

If you can stomach the Sportsmobile design aesthetic, that probably would be the most practical way to go. What about resale/trade in though? The OP is new to RVs, so there's a chance they'll decide RVing, especially in a class b isn't for them. In that scenario, wouldn't an upgraded roadtrek/pleasureway/winnebago/etc would be easier to sell than a Sportsmobile?

To me, the below floor storage is a huge benefit, as they can use up half the inside with batteries and such. Since no generator, there is lots of room underneath. I would not put them inside, even if I had to get the underbody mount done by someone other that the installer. I hung 440ah of AGMs under our Chevy without a problem.

The "hang below but access from inside" design that GWV used is pretty optimal, IMO:
