Secured to your trailer
ultimately you want the body tied down and not the supension. figure out how to put an eyebolt/u-bolt on on each corner of your hotrod. install the same on your trailer. use nylon rachet straps to pull the body down and cross the straps. each strap should cover the weight of your hotrod(dot rule). by pulling the hotrod down you don't over heat the shocks and springs or wear them out prematurely. by crossng the straps the hotrod doesn't move around at all, even if there is a mishap.
