I use a made to length strap that I use over the front frame member and in a V to two floor mounts -this lets me winch the car to the same area every time amnd I hook it up-let off the tension from winch and go to the rear where I use 2 padded short straps , one over axle housing on each side of pumpkin, hooked into a ratchet strap angled out a bit to tie downs pretty much located about 4 feet apart and relatively about rear bumper so I can easily reach , tighten or adjust-these two rear straps are super important to hold vehicle during stops with the truck/trailer------front is restrained with the v strap plus a barely slack winch cable-

I also on race car ( Pro Stock ) snub/restrain the rear from bouncing on trips where I know the ride might be ruff-----( at one race years ago, the rear shocks were hot on a friends car at arrival at the track -didn't qualify well!!)

It is important to look at several factors when towing , and many peeps ignore or are just stupid/ignorant about the load balance on the trailer so as not to effect the drivability of the tow rig, and/or create a load unbalance that results in the tow rig plus trailer shock/spring causing severe bounce/ wobble( talk abut need for cross strap?) with the being hauled DIAMOND on a rig just barely acceptable for a piece of COAL. Also don't forget to consider the side aero impact of meeting/passing/being passed by a Big Rig / Bus
