I use a set of Yakama Hully Kayak rollers. They are mounted to a piece of that smooth white cutting board stuff and then that is clamped to the crossbar with hose clamps. The cutting board works as an interface plate since the mounting holes in the rollers are wider spaced than the width of the rack cross bar. It also works to keep the Revo from getting scratched until it is up on the rollers but that's likely not a problem with the wide PA.
Lift one end of the kayay up on the rollers, lift the other end up and push it into the bed. On and off the beach in just a couple of minutes.
I fish a lot at night, hence the trailer lighting.
