Check Northwood. My 2008 Arctic Fox has aluminum superstructure and marine plywood subfloor. The aluminum frame has wood inside the aluminum at points where things are screwed to the frame so they don't just put screws into the thin aluminum. The trailer frame is very stout. Northwood makes their own frames in house. It is a true, four season trailer. I have camped comfortably at zero degree temps. My 29V has two slides, a rear full queen size bed, center bath and lots of wardrobe space and lots of kitchen counter space. The dinette seats four, there is a counch and swivel rocker, in the living area. The bath and bedroom and refer and sink are all accessable with the slides in. I am replacing the swivel rocker with a comfortable, folding camp chair. Afer all these years of wrestling the swivel rocker around, a folding chair that can be stowed will make it much easier when traveling and just stopping over night to move around in the living area without putting out the slides.Northwood trailers have huge CCC which, if you read the current post on empty weight vs GVW, you can see is important. The 29V, which, sadly, they don't make anymore, carries 67 gallons of fresh water, has a ten gallon, gas electric water heater and gemerous holding tanks. All the tanks are inclosed and heated.In a used unit, condition is critical but, so is original build.
