Before you shop brands, you should learn about features. What do you know about residential refrigerators in RV's, Never Lube Axles, self adjusting brakes, greaseable spring shackles, ducted air conditioning, fantastic fans, electric vs. manual awnings, four season packages, heated holding tanks, aluminium vs, wood framing, tow ratings for your vehicle, 13", 14", 15" and 16" tires for the trailer, electric vs. hydraulic trailer brakes, different brake controller, sway control hitches, weight distributing hitches, aluminium siding, fiberglass siding, rubber roofs, and the list goes on.
You get my point. Learn about all these things and more; then buy the trailer that really suits you.
