I discovered pretty early on that it was worth more to me to keep it simple. Light reliable rig, not a 3 ton truck. The reliability and flexibility of a $20 water bag with a hose on it, vs plumbing. Same for a portable stove vs built in. Camping in remote areas where toilets are unnecessary. Camping where the climate is nice so heating and cooling aren't needed (easy to do year round in the western US). Nothing like bathing in an ice cold stream on a sunny day! How much solar do you really need and for what? Many modern conveniences aren't worth the hassle even in a permanent home. No way do I want to hall all that crap around with me....The better built trailers aren't so bad, they get bounced around pretty bad as trailers. You need to stay on top of maintenance and plumbing. Anyone expecting a hardcore expo rig to be maintenance free is in for a wild ride.
