That’s sound advice and probably much more practical but I like to try to push the envelope if I can find a way to make it work. I also don’t want to be having to run in for propane refills frequently, the tank is pretty large. It’s not as if I could pitch it in the back of the truck and go trade it in at Blue Rhino or anything.
I know this may sound obvious, but you said you had a well with a panel. Do you have 220 already coming onto the property? Worst case you could add a 30amp circuit to the panel and you could run the coach with it including 1 a/c unit.
If you only have 110, you could get by with a small heater in the coach, but you’d have to run the generator for the a/c.
Since you are going to a static site, what about wind? you might find the technology is more advanced for wind to accomplish what you want to do.
If you want a good resource for your application, try RV.Net. There are people that have probably tried every application to go off the grid and will be willing to help. Good luck.
One last thing...if this is being set up for Hillary amd Bill to go on the lamb, disregard anything I said previously.
