I think the future of RV's will be a move to more automotive like construction. Super lightweight materials, monocoque construction instead of heavy frames, etc. That would probably require a complete revamp of the industry business model and make them much more expensive, but maybe better quality. Could you make a decent travel trailer from blown polystyrene with carbon fiber elements and spray foam insulation? I can see a million ways to make RV's lighter and more reliable, but they would be completely foreign to todays typical buyer. Would you buy a plastic egg to camp in?
LOL, we did camp in a plastic egg for 3 years (13' Trillium 1972) until it just got too small. Still, it was 40 years old and I wonder how many of today's trailers will still be going strong in 2052? Good times in our little egg, and not much to go wrong.
