My wife & pick the Wildcat 31TS. It floor plan is what sold use. Quality is about what you pay for in a Mid-level 5TH wheel. IT pull ok , we have the Trail-Air pin Box. As for the roof joist, Some say the Aluminum is like a heat sink in the cold. We have own TT & 5th for 30yr now. We just pick what work for us & we think will last. Most of trailer are coming with a little more stander stuff . What I would look at is REFG, AC, Water heat, Axle , furnace & slid out . We had a HR TT All Aluminum frame, but to get a cup of all thing in the morning , I had to step on everyone to get there. Get what work for you & enjoy.
