I think the tire straps are the best option. I use it on my motorcycle with a wheel chock and it never moves.
But I have wood floor slats and little confidence they will last even if I drill the holes before installing screws in the E tracks.
So, to center it and lash it down, I robbed the self-retracting straps from my old trailer and fabbed up and pivot bar today to get the 700 and the golf cart centered on my new 6x12 trailer.
The trailer is already front heavy and both vehicles tip the trailer 3-4 inches before it hits the pivot bar.
I made it with a 24 1/2" gap in front for coolers/bikes or whatever.
The manual winch is a left over from my old motorycycle trailer. 1500 load limit, it should pull up a dead utv or cart.
Lastly, cut up some spare E tracks and welded them in the rear corners of the trailer.
Low profile when not in use and one in front just for the hook on the trailer winch.
Getting ready for a beach trip!
