I have had trouble strapping down vehicles in trailers from the very first time I tried it. It does not matter how tight I strap it down they dance sideways on me. Last year I even broke good ratchet straps because I had them so tight. The little green machine is only 2,400 lbs and I still could not keep it from moving.
I kept asking and searching until Powerboatr post this LINK
. These people have everything you can think of and a whole bunch of things I could never imagine.
This is a picture from their website. I ordered four of these to strap down the car in the trailer. A regular wheel strap would not work because of the low clearance on the car but these are perfect.
I installed the etrack...
We pulled the car in and strapped it down..
I have pulled the trailer with the car strapped in with these for over 560 miles over some pretty rough interstate and the car has not moved and inch that I can see. It sure looks like I have found a solution.
