I decided on the Starcraft 14RT OFF-ROAD trailer when I was looking for camping off the power grid.
When we need to operate something on the picnic table we just run an extension out to it...
This is high off the ground and will go anywhere my 4X4 truck will go. Actually will cross a rock bottom stream... The front deck gives us plenty of room for bringing alone some serious camping supplies.
We have all the nice things inside including cassette pottie and shower unit.
With some upgrading of the battery system we can stay out for days on end and camp very successful off the batteries. What we did was figure out what we wanted to have for camping off the power grid, beefed up the battery system to include a smart-mode controller/charger, more batteries, bigger charging cables and battery components, changed over to LED lights, installed two PSW Inverters (One 600W PSW Inverter to operate all of the home entertainment items - a bigger 1500W PSW Inverter to operate bigger 120Ac items but it is really more of a back-up since it draws so much current loaded down).
With all of this we do almost what we usually do at camp sites with electric power with the only thing we do without being the air conditioning. What makes all of this work is the next morning during breakfast we have to re-charge the batteries using our 2KW Honda Generator by connecting the 30A Shore Power cable directly into the generatorr 120VAC receptacle using a RV30A-15A 18-inch long "dogbone" Adapter (Walmart). We can re-charge our battery bank in as little as 2-3 hours of generator run time. This satisfies the generator run time restrictions we usually find at most of the camp sites on the east side of the US. We will run the generator again around 4:30PM to 7:30PM to seal in a good 90% charge state so we can do all of this all over for the next day/night battery run. With what we do our battery consumption is around 250-275AHs. usually in the morning the battery banks reads from 12.1VDC to 11.9VDC which is close to 50% battery charge status.
Works good for us camping off the power grid. It is more fun doing it off the power grid.... Of course at my age we usually do a lot of sitting around the firepit poking the fire, feeding the squirrels, and drinking fresh made ground up coffee beans coffee.
