Best Way to Tie down ATV to Trailer

[Freedomflyer 1,886]

I went with the Erickson wheel chock tie downs, bought some etrack at Harbor Freight for the rear tie-down. Quick and easy, very secure, never had them loosen,  let's the bikes bounce easily on front suspension,  rear just helps keep them in place if it is a really crappy road to the trail head. Never had them come loose, front end has never moved, rear very little. They are bolted on all the way through the trailer deck, some of the bolts even go through some of the metal cross members of the trailer.
