@Ceili,
I know weve got some piucs somewhere. They were film so Ill have ta scan em when I get em.
Dont stretch it cause the frame is secure and the glas shell wont adhere together without significant weight from wood frames.
You could stretch an AIrstream but I wouldnt recc one of these.
The taking everything out and starting from a hollo shell that you resand and either paint with a "tip and roll" (sorta like we do for boats, or spray with some acrylic or lacquer for really funky graphics .
I always wanted to put some wooden sides on ours to make it look like a "woody" but that was just too much waste of time when I really mneeded to get new flooring, cabinets etc.
The issue about the shower, and outside shower with a frame for a wrap around curtain serves well and you can have one of the little on demand gas heaters . A hot shower is always needed. Of course, for rough camping, we only had a porta potty with a curtain kit that we got from some RV store.
THE only problem I recall was that the wheels were way too small (13'0. yours look sorta like ours. hat would make it wobble in tow. SO I got some stabilizers for small cargo trailers and that steadied it right up. You cant tow these at 80MPH becuse if a tire ever blows youll flip the damn thing.
Write to CAMPERS world.com they have all kinds of after market stuff for refurbing an old camper.
