Jet Ski ramp for the pickup bed?

Yep, hafta troll some boat part sites but one of the last boating parts catalogs I got in the mail had a couple. I think it was Marine West, not positive tho.
One model was a sliding tray that pivoted down at the tailgate, the surface was Teflon coated.
The other model was carpeted and just had a ramp you prop against the back of the truck.

There was a picture for bedrugs product that showed one in the back of the truck. I always wanted to do that to my old f150, but Buying a trailer was a whole lot easier.
