When I was on the road with my dirt bikes, I had an enclosed trailer with wheel chocks, and tie down points inside the trailer to suck down the forks. Bikes were not much over 200 lbs. They never went anywhere. I use to haul them in my Toyotas pickup bed also when racing events in New England. I just secured the straps hooks to the steel anchor points in the front of the bed. Once socked down, the bikes front tire compressed against the bed, so nothing was going anywhere. I had to leave the tailgate down, as the rear tire would be there.
