Dutchmen TT

we are looking for a TT to purchase - price range 8-11k. today I looked at a 26' 2010 Dutchmen Rainer. it looked OK but the slideout was in the sink/counter area and the counter was not level - one side was about 2" higher than the other. is this normal? I also noticed a big dropoff on the bedroom floor along the same wall. floor was really sloped towards the edge of the wall. I looked under and it appeared one of the support flanges was bent and the side of the trailer bowed out a bit. I could not tell if this was due to an accident or if this was just a weak frame design. the seller did not know anything about it. I decided to pass.

there is a 2004 31' Dutchmen classic I want to go look at but its over an hour away. am I wasting my time on this brand? are they known for structural issues or other major problems?

the 2005 Layton went to see literally had sold 10 minutes prior but it looked amazing with 2 big 3' slides.

btw, I am not new I currently own a 1997 lance truck camper and have owned 2 others before this one. I am handy and do basic repairs and will not take it to the "dealer" if some trim piece falls off or comes loose for instance.

thanks!
