It's an incredibly sturdy trailer I probably built just for U-Haul. I visited several mega trailer lots in the area and found nothing like in galvanized. One dealer had an open trailer, 6ft-10in x 9 foot for a killer end of model year price so bought it. I was primarily for my sidecar rig but I also mounted a Condor chock quick disconnect base for two wheels.
I've had two enclosed trailers, both by Pace and found them to be of marginal quality but "good enough". To me a box trailer with ramp is the way to go but can be very spendy. If I can find one wide enough to accommodate my hack I'll replace the open trailer.
