Yeah, I had bought the gray one from Harbor Freight a few years ago and mounted to the motorcycle lift I purchased also from Harbor Freight. After about a year, open garage door and 2004 Road King was leaning over about to fall off stand. Grey chock was bent and twisted. Not garage proof, certainly not trailer proof. Going to see if local HF has one in link you sent. Thanks
Welcome. A couple of buddies were using the grey Harbor Freight chock, no problems. After about a month mine bent. Took it back to Harbor Freight, got money back, manager suggested the chock in the link. Much better construction, left the bike in it in the garage unsupported, not strapped, for extended time periods when I was traveling too much for work to ride. You may not need to add the plywood, mine worked ok without it but was smoother on/off with it. Can use the 2 eyelets on the front as tie down points, but always had it secured also by straps to the front of the trailer.
