You might read 100 bad reviews online, many of them duplicates from angry people who post everywhere. When that number of bad units is taken in the proper perspective, with 500,000 trailers manufactured annually (actually there are many more than that produced each year) the number of "bad units" is so small that it's not statistically relevant (unless you're one of the owners of a bad unit). Chances of that happening, given half a million produced every year are so small that it's just not something any owner should dwell on.
Go, enjoy, deal with the issues "IF" they happen, otherwise, focus on the good, not on the "possible bad".....
There are enough hypochondriacs worried about health issues, we don't need RVchondriacs getting mixed into the fold
