Hi Brad, and welcome!
I have had a half-dozen brands and sizes of fiberglass RV (plus another half-dozen of "other" trailers/mohos) in the past few years. I personally find the amenities important because of the way I use the trailers, but I will suggest that a good night's sleep is THE most important part of finding a trailer that works for you. As a 6'5" tall person, I can tell you that if the bed is too short, or not wide enough you won't sleep well, and you won't enjoy using the trailer. Standing height isn't all that important as you don't stand often (except to cook or do dishes, of course).
