Each brand of trailer has its own pros and cons. I've yet to find a 100% quality trailer.
If planning to keep the RV/TT for < 5 years, I'd focus on floor plan. Most quality (or lack of quality) items appear after 3-4 year mark. For example, leaky windows, leaky roof, screw heads letting go, etc. etc. Yes. One might have a few initial burst of "fixings" (stuff missed down the factory line) but the out of warranty expensive items will most likely appear after 5+ years.
Besides floor plan, do look a feature as well. My Jayco has a white color awning. Being white, it shows every fly poop and spec of dust. The CrossRoads trailer across from us has a brown color awning material. He only needs to wash his awning 1 x per year (instead of every 3 months). I like the CrossRoads roof better than my Jayco roof. Their roof has a better convex curve and their trailer gets much less black streaks (due to better roof material). They like my Jayco's layout much better (compared to their CrossRoads). Thus… Pros / Cons when comparing against each maker.
Bottom line… Just like buying shoes, which maker "feels" best to you?
