While a trailer is certainly nice to have, I manage without one & saved some cash. I have a ’93 Silverado extended cab with camper shell. Because of the shell, I can’t shelf it like Cory due to the limited headroom, but the bed is wide/long enough to fit the kart by removing the side & nose pods. The bed can still accommodate miscellaneous stuff, & the extra cab space allows for stowage of tools, the CIK pods, gas & air cans, etc.
A key piece of the puzzle is the “kart carrier” I bought from Tim Koyen to carry my KartLift along. It locks into the hitch receiver to carry the stand at the back of the truck.
The key is having a bed big enough for the kart. Figure L x W of approx. 6′ x 5′. Keep in mind, a 53″ wide CIK rear bumper isn’t – & shouldn’t be – a quick detach component, so if your kart has one, that will determine the min. bed width you’ll need.
