Myself, I'm leary about buying a laminated trailer. Seen so many delaminated trailers on the dealers lot when new, at the campgrounds, and on the road.
I would go smaller for the bit heavier Stick and Tin models and not have to worry about delamination.
After all you really aren't saving any real weight in most circumstances. They put in smaller holding tanks, lighter duty frames, smaller propane tanks, and then are only saving around 500 to 700 lbs lbs. Load less, bring less water, and you may not really need an Ultralite camper.
