imho goldrush, T&E and the like are top of the line, featherlite, ATC are down a grade from them. when i was researching aluminum trailers iirc i saw some bad feedback on the optima and exiss. i ended up with a 40' ATC goose it's a nice trailer but there are still some things that to me weren't acceptable.

personally if you can swing the cash i recommended an aluminum trailer over steel ALL day long...and you can keep the wooden floors they're OK for a tree fort but i hate them in a car trailer. also if you've never pulled a goose or 5th you should try it compared to a tag...i think you'll like it
