Tailgate loading issues?

[Davidw2415]

Only way I would think it to get by would be to add a 3/4" plywood sheet to the bed overhanging the tail gate of the pickup and then replace the cables with some chain IF YOU HAD TO USE THIS METHOD TO HAUL THE BIKE.

Just a thought. If you do the plywood thing may you could attach a couple od 2X4 rails to it that tire would fit between.
This would add strength and help keep the bike in place. And
maybe you good lay some weight such as a couple of sand bags toward the front to keep the front from flipping up while weight is toward the rear. Hope this might help.
