I'm also looking at Northern Lite for the construction and a true 60x80 queen bed and 6'8 interior height.
I like the one seam fiberglass but still concerned about delamination. I know maintenance is key to keep water intrusion out.
I know what water does to structure. I've been around the water damage business all my life.
I've been looking at Eagle Cap and Cirrus construction. Aluminum frame, fiberglass sidewalls with azdel composite backing. Might be wood inserts in the aluminum tubing so a screw will take a bite but I think that is all the wood in Eagle Cap. Cons are massive seams to maintain on these two campers.
Wish Northern Lite would treat the wood with something to keep rot away or use aluminum or composite like coosa. Hallmark uses coosa
