Need to borrow / rent small enclosed trailer

We are heading out to MotoGP Indy again this year and are hoping to take the bikes down again. However, we want to use an enclosed trailer this year as the open trailer we used last year ended up causing quite a few chips in both bikes. We need something around 6x10 or close to that since it will be towed with my Jeep Liberty (5500lb tow capacity). One with brakes would be ideal, but it does not have to have brakes. The time period will be Wednesday 8/15 through Tuesday 8/20.

If anyone knows of anything please let me know. I looked into Uhual but they want $70 for 6 hours for their enclosed trailers.
