EXCEPT for buying the correct length and weight for your tow vehicle most RV'ers make their decisions on what TT to buy based on lay out.
The DW wants such and such and the DH wants what he wants as far as the lay out of the trailer. Just look around at all of them until you find one that suits both your needs. Same as how people buy a home.
Length and weight that fits the specs of your tow vehicle is number ONE.
That narrows your search to ones that you are able to tow SAFELY.
Then the layout. Just go shopping and look at them all.
Asking what brand is better will just net you each owner saying the one they have is the best! :W
