Seeking advice on Cougar Lite (1/2 Ton)

We have a 28SGS. Love the layout , it had its fair share of problems in the first year, all repaired under warranty, but its been fairly good since then although not perfect, have had a few plumbing issues where the water supply connections come into the unit which I repaired myself.(might have been frost related although it was well winterized) We have put about 35,000 miles on it since we got it in Aug 2014 as a 2015 model. Its been from Ontario down to Arizona and up the west coast to B.C twice now, easy to tow and a nice size for parking and camping at State and Provincial parks which is where we do most of our camping. I would describe it more as a mobile kind of model rather than a park and stay model, as we rarely stop any more than a day or 2. On the run to B.C we are there and back in 3 - 4 wks.
