? on quality of Forrest River Sunseeker

been looking for a C or A under 30ft,,,seems every one I see used is junk...looking at a used 2018 FR Sunseeker 2290S,,,one slide...price is 50k...
Miles 18k....
I think he said these have fiberglass roofs...I know people here say stay away from Thor but how about Sunseeker ?
