Even for an entry level trailer, we have been pretty happy with our Sunnybrook (Sunset Creek). I don't know how they've been since Winnebago took them over, but they had the lowest employee turnover rate in the Midwest at one time. I toured their facility right after Winnie took over and the new units looked pretty nice. When you consider lightness and cost as the primary factors, It's hard to build quality without making it heavy. My biggest gripe is even the small tasks involved in building trailers get fubar-ed. I mean, how much longer does it take to properly drive a screw to do it's job than to slop it in sideways and miss the intended component? Goes to pride in workmanship I think. As far as I can tell, they're all varying degrees of junk. If they made them too well, you wouldn't need to buy another one. Or the cost would be prohibitive. The markup on trailers is obscene. As stated, if we continue to buy junk, they'll continue to make it.
