I had the chock mounted in an open flat-bed trailer. Then I acquired an enclosed ramp-back trailer with the same chock already mounted. Works great, simple to use, easy to mount. This chock hauled a DRZ across the state, easy peasy. The other has hauled a KLR and an Africa Twin around, handily. Drive the bike in, strap her down and go. Nice to have if you already have a utility trailer and you don't want another dedicated trailer just for bike transport. Chock capacity: 1800#. Ramp capacity: 800#. Chock mount bolts are under duct tape.
