FYI
here's what I do and recommend and also because its the rules. use 4 straps that are each rated at the weight of the hotrod. each of these are tied to the frame and crossed to the opposite side. the trailer chains are 3/8" link and cross over to the opposite side to the hitch. this is so if the ball fails or the hitch lock comes loose the trailer tougue will fall into the crossed chains and follow the truck and not sway all over the place until you can get everything stopped. also use clevises instead of the "S" hooks to attach the chains to the hitch. I have a battery operated brake switch in the event the hitch comes unlatched or ball fails. this sets the electric brakes and will stop you. I also use a pin or lock to make sure the hitch does not open. I also have a back up alarm to notify everyone around i'm backing up. safety first, you have a lot of money tied up in your hotrod and trailer and do not need to lose it to a wreck. these are also DOT rules that if you do not have all the stuff you could be pulled and fined and have to leave the hotrod where it is until it is brought up to the standards. some of you have different opinions on this and it is up to you on how you want to tote your hotrods but just give it a little thought before something goes terribly wrong.
