Googling the brands will bring up issues with every one and usually the issue is amplified by the inaction and/or incompetence of the dealer's service personal.
When I was researching for a fiver last winter and spring, I gave up trying to find a leading quality brand, seems they change names faster than the rating systems can keep up with them.
My wife and I visited several dealers looking for the quality brands, that was fruitless, sales people were interested in selling what had the best spiff for them.
We then visited camp grounds asking campers not only their thoughts on trailer brands but on dealers. That was very interesting to say the least. We went with a coach that had a good following, was well spoken of, was designed for full time living and all season. After a season of camping, the dealer was a nightmare to deal with for warranty repairs (no surprise, it was expected from our interviews). The handful of issues were minor so I just fixed or adjusted it myself.
