I bought a Can Am commander 800R 5.5' wide/10' long/72" high- it is 72" at the top of the roll bar-
what you need to pay attention too when looking at trailers is the Door opening height. has to exceed 72"
I called around DFW/Houston/Austin etc etc Inside Height was ok but the doors were too low on 95% of them
Found a single axel enclosed 7' x 12' w/76" door 2015 Cargo craft EV7121 @ I-35 Trailer store in Lewisville approx. $3000
the only thing I had to add was D-Ring tie downs (qty4)
you may want to consider a 14' as there is minimal space left on the 12'. Mine will just be left @ the lease as a garage and will not be towed back and forth so extra room was not really needed for me. ( in fact just towed to lease last weekend )
trailer was cheap to insure $50 year / Can Am cost approx. $500 year to insure but it covers anything or anyone-anywhere.
