School me on trailer towing I just bought an 18ft car hauler to haul my cobra with my raptor. How far forward should I have the car on the trailer for safe hauling? Also the trailer is rated at 7000 gvwr, I have two hitches, one rated at 6500gvwr that came with a ball to match. I also have one that came with the truck rated at 7000gvwr but it doesn't have a ball. Should I use the 6500 or find a ball to match the one that came with the truck?
