we have a 16 foot enclosed trailer we use to haul and camp in when I had my RSV I used a harbor freight chock and I installed D-rings close to the wall then I would ratchet strap the chock to the D-rings and the bike to a different set of D-rings, never had a problem. now that I have my trike I do the same thing without the chock. I still carry it in case I have to retrieve a broken down bike. I like the chock with the brace across the front no twisting or movement with the ratchet straps holding it in place and no problem to remove.
