I've never had the straps get any slack when hauling the jeep on the jeep hauling trailer with it strapped to the frame. Back of Scott's trailer must be rougher. Next time it goes on there it gets strapped down by the axles. I think the angle of the pull on the twisted hook (carhauler straps) was the reason it broke, they just don't work right when hooked to the stake pockets. I strapped the jeep to the multipurpose recreational vehicle hauling trailer by the axles this weekend and it rode fine, could not notice any bouncing. I did have the winch line attached but not tight at all.
