I use this
one for my Goldwing in my 19RR. I selected this one because I didn't want to put anything into the floor of my trailer to mount it. I take two straps through the triple tree in the front and two straps from the chock to the rear tie downs and she doesn't move. Good luck.
For my cargo trailer I'm going to use this
one (and that's only because it is a plywood floor and I don't mind drilling into that one. The cargo trailer doesn't have a lot of room to move around in and I can't get in front of the bike to tie it down.
