Thanks for all the good advise and responses.
One of my problems is time. I need to be back in the camper this weekend and for the next several weekends. And hopefully this is the last week that I will be needing the AC. And I will also have it set up boondocking style, so no shore power, just my Honda 2000.
My quick fixit plan is to buy another battery (in the wire burnout, the old battery top melted out) then wire the water pump directly to the battery. Charge the battery with my Honda 2000 and a small charger. Run the water heater from propane. That will get me water, toilet, and a hot shower. I have a Wave heater plumbed in, so I have propane heat. I'll buy some cheapie battery LED lights and stick them here and there. So I now will have lights. I will just use a Grizzly ice chest for my fridge and I'm all set.
I'll try to fix everything after bow season when I have more time... Sure would be nice if I could tie the battery straight in to the DC fuse box.....
Thanks again,
