We have kart stand that after loading your kart in the truck, you put the stand in your hitch. We also have an adapter that will exstend out allowing the tailgate to be left down for more bed room. Works very good, I use one when I run to the track to test.
Give me a call if this is something you asked santa to bring you. I can show him where to find one.
Happy Hollidays
