Never owned a class A or a golf cart but have worked on a lot of them and a lot of lawn tractors. The usual problem with loading anything like that into a truck bed is have the correct ramps. The traditional 2x10 boards present a sharp edge at the tailgate to hang up on. The correct ramps to use are crowned so it's a smooth transition. Many are made of aluminum and have chains that attach to the truck so the ramps dont get kicked out. I would be sure the attachment method is bullet proof as far as not getting kicked off the tailgate.
