I'm in the process of running a #0 cable bumper to bumper on the service truck I just bought to power a plug-in jumper cable connector on both ends. I'll have a set of 20 foot booster cables, also made from #0 welding leads. The truck will be equipped with two Group 30 batteries wired in parallel and a 100 amp alternator. The same connector on the rear will allow me to plug in and power the winch on my car hauler trailer.
