What is it you wanna know? Whether long or shortbed, you won't be able to close the tailgate. With the shortbed though, if you do it enough times and you will definitely bow your tailgate. There is a Technical Service Bulletin out about this and you can get your tailgate reinforced, but it may happen again. Also, if you've got a model year 06 or newer, get the aftermarket D-rings for the bed. It makes tieing your bike down a lot more secure.
