I had my P-body come loose in the enclosed trailer.. a slick went
flat.. the fronts were crossed and the rears were straight... the
right slick went down and the strap went loose and the strap
bounded off.. car bounded to the right and that strap bounced
off.. at least it didnt go forward being it was in park.. I had to redo
both sides of the car.. now I just put a bungy between the 2 rear
straps.. that was the only issue I have had
