"Fiberglass construction"?
What does that mean?
There is wood construction with fiberglass panel outer walls. In some opinions that looks way better than the corrugated aluminum outer walls.This is not fiberglass construction.
Fiberglass construction is a camper that looks like a burrito on wheels or a white airstream-looking camper, a true fiberglass construction,
Sometimes instead of wood construction it will be aluminum studs.
I have walked a lot of junk yards looking for parts and seen a lot or wrecked, damaged, delapadated and falling apart campers, both motorhomes and tt. I would not sweat too much about wood or aluminum studs or how close or far apart they are. The walls are held up by the interior build-outs (counters, cabinets, inner walls etc).
They are all junky, but hold up just fine for regular driving down the road or when parked. They are built to minimal standards of durability.
