That is an all-new floorplan by the looks of it. Interesting!
We have the same size, but different model in a Flagstaff.
-lightweight for the size
-fit and finish are second-to-none in the price range, and very good regardless of price
-relatively easy to pull, rubber torsion axles seem to ride nice and smooth
-seem to be well-built. We have had no problems related to the construction. Actually, we have had very few problems of any kind.
-it is a lightweight, so all construction reflects that
-the frame is very light, adequate for the job, but cannot be used to pull a boat behind
-no roof rafters, but still seems strong enough
-no regular plywood on the floor. It is a bonded "sandwich", thin plywood/aluminum frame insulation/thin plywood. They used to have an issue because the "plywood" they used was too thin and cheap, and the floors failed. But I believe they are now using a reasonable thickness. Still not like the heavier campers that have 5/8ths plywood on the floor, but seems ok.
-Exterior walls are thin to save on weight, but the insulation value is lower because of it. So it does take more to heat and cool. We live in moderate climate, so haven't been too bothered by that.
So overall, if it is a lightweight camper that you are shopping for, the Rockwood/Flagstaff line is a good one. We are very happy with ours, and would have a hard time finding any reason to look for something different.
Good hunting, and welcome to the forum!
