Similar to cars, every brand/make will have it's mix of lemons vs. no problems at all . You can try to pay more for a "better quality" brand, but that's no guarantee you'll not have defects or poor construction issues. Research will show plenty of consumer complaints about any brand, so don't let that be too much of a factor. My advice is to find a floor plan/length you want then go look at the options and determine for yourself if that particular rig looks good for you (quality, layout, etc).
We just got done with trailer shopping (second TT). Based on our research (online and RV shows) I thought we were going to walk away with a Jayco, but after a lot of perusing we ended up going with a more expensive Outdoors RV based on various things. It's not without it's defects either, but so far so good.
My DW had me looking at Forest River trailers as well and the options the dealer had on the lot did not impress me. That doesn't mean they're not ok, I was just looking for specific things besides build quality (enclosed underbelly, holding tank clearance, etc. ). Most dealers will only carry a small subset of of options produced by a manufacturer as well, so one model from a manufacturer may not be the same as a different model carried somewhere else. FWIW. Good luck on your decision!
