Have had two toy haulers; current model is Work & Play 30WRS. I did NOT want to drill holes in the cargo area floor for any chock. I tried several types of wheel chocks but all had issues. My good pal ordered one for his Indian. Said it worked great. So I ordered one for my 05 CVO Fat Boy. It is solid, works easily. A great piece of design and manufacturing. The big test came on its first use in my toy hauler.
Even without being "bolted to the floor", the Wheeldock did the job. The bike rolls in, the wheeldock stays put. The others all would move forward if not bolted down. My wheeldock did move and inch or two laterally after my rig hit a massive "heat heave" on I-95 in South Carolina. But, with proper cargo straps and secure hooks, the bike stayed where it was supposed to be.
Sturgis is next; almost 2,000 miles from Saint Augustine. I have no worries with Wheeldock. It's worth every penny. The others? Just junk.
