Same here. Our 2008 works great for us. A 24ft with two ample slideouts. I can't find the source of one soft spot and another in a wall I took apart, cleaned out, and redid (small and easy fix).
I hate the roof air and always have. Too big, too noisy and I can't run it on my Honda 2000. I want to remove it and put in a dome, remove the microwave, and put in a window unit in the cabinet.
It probably needs a leak test and it needs a new awning. How much is all this versus a new travel trailer? I like what I have and am willing to spend a couple of thousand to have it last another 5 to 7 years (or more).
If I were to buy something new, it would be custom. No roof vents, no roof air, antennas, refrigerator vent or decals. A clean flat roof and clean sides.
