Thanks for the tip and well wishes. I know its over the top for a small travel trailer, but I actually have the budget to have some fun with it. We bought it 1/2 price and had the budget for a new one, so theres some room to play with ideas right now.
Definitely going to cram as much XPS sheets into those tiny walls as I can!
You're welcome. For sure have some fun with your project. The really nice thing about restoring a travel trailer is that you can outfit as YOU deem nice, not as something that sells quickly or shows well at the RV show.
What I did with the insulation is (from exterior to interior):1" fiberglass batt against inside of aluminum siding,compressed, 1" extruded polystyrene, polyethelene 4 mil vapor barrier, 1/4" fanfold extruded polystyrene across the wall and ceiling surfaces (acts as a thermal break). I used the fiberglass batt against the siding so some air could exchange, allow for water drainage in a leak situation, and allowed for wiring installtion. The foam board panels were individually cut for each frame space with foam adhesive recovering any possible leakage into the frame. The vapor barrier just makes sense. The fanfold-thermal break keeps the inside paneling warm in Winter and cool in Summer.
Results: I can heat the trailer in MN, in the Winter with a single 1200W electric heater.
Good luck with the project and keep us informed!
