Here's a thought: Let's talk about weight.

How much of the "stuff" in your camper is made of wood? How many of the things that are there do you actually need?

You could lend thought to removing some of the unnecessary components, which will definitely help out with mileage, engine loading, etc..

Most of the wooden stuff in there can either be replaced with tin pieces, fiberglass, or plastic, depending on it's actual job, and how much use it will see.

Basically, anything wood could/should be replaced with metals or glass/plastic composites... this will probably shave a good bit (a few hundred pounds) off, all by itself. Getting rid of anything that doesn't really need to be there will save even more weight, and you could probably get rid of up to 500 lbs just by doing this. 500 lbs is probably about 1/8 your camper's weight.

You can lessen the electrical load by replacing the lights with LEDS, as well, except the headlights. This could save a large draw off the alternator any time the lights are on.

Can you walk into the camper section from the cab of the truck?

I've often thought about building an RV out of an old U-Haul van or something... I might still do it, someday.
