It fits in the clothes cabinet. I have a portable solar panel rated at 200amps. I also can charge it from the 20amp outlet while driving. For boondocking you would need to be careful and use the propane when you can and hopefully have good sun/or add another portable pane. We love our RT. It only has 32K on it now and we already have done a cross country trip, LA to Vermont and back.

That solar generator is a 2048 watt hours so about 170ah and that won't run and air conditioner very long, maybe a bit over an hour as long as it doesn't cycle and trip out from low voltage after the battery gets low.
I seriously doubt you have a portable solar panel that gives 200 amps as that would something like 2400 watts.
It is probably 200 watts that with good sun and efficiency will give 10-12 amps in most cases on average and 60ah or maybe a bit more ah per day on average.
Probably OK for an occasional microwave run and other loads in the van. Vans with propane frigs usually seem to use 15-40ah per day depending on how you live and use power, so frequent charging from shore power or driving is probably need as the solar probably won't keep up if an AC or more than a few short microwave runs. The solar will likely keep up with your use without the high drain AC and microwave uses, though, unless you get a few days in a row of bad sun and no driving.
