I think this drawing better details using the DPDT switch in this application. There is no sharing of ground. If I can find a 12v thermostat that can handle 30 amps, I may go that way. If anyone knows of one, please send me a link. Thanks!
Re: grounding. AC hot and neutral run as normal, the ground goes to chassis. All my plugs are GFI.

Thanks 1der. Had a feeling that the AC ground should absolutely be tied to the van where most shorts would occur as well as any metal conduit or junctions etc. And yep, the first thing that AC line should head into is a GFCI, either outlet or breaker or both.
This thread also discusses the midnight solar kid dump load feature...that's what started all this....
I'm always interested!! Thanks!
I may have actually read that one, but a refresher is always in order. I have some serious building to do coming up and gathering knowledge is always the first step.
The new diagram no longer has a ground issue, but you still will most likely have a problem sharing the breaker, unless it is a dual purpose AC/DC breaker, but I expect not. Also I expect the existing T-stat is 120 volt AC?
You can use a lower rated DC T-stat to control a higher power relay for the 12 volt element. Actually, i guess the 12 volt T-stat could control both a relay for your DC circuit and for your AC circuit. That would put you back to one T-stat to control both elements?
feel free to pm or call if you want to bounce off some ideas.
