Full Throttle OG
I'd love to get one of these, they look great and they're free if they deliver a 1MPG improvement. Don't think they'd work too hot with motorcycles and mountain bikes though, I'd hate to have the rear window blocked so frequently (and lose the backup camera with gate down).
Depending on how you secure the bikes, you can secure the cover in the folded but flat position. That may or may not work if you have to get the front wheel all the way to the forward wall of the bed. Worst case scenario, you could always mount a secondary backup camera somewhere on the bumper.
