I noticed that you don't have a roof ladder on the back of your truck and have your tailgate sticking out past your camper....BUT if those weren't the case you could mount some Quick Fist connectors to the vertical rails of the ladder and strap your skis onto those. Heck you may even be able to bolt these directly to the back of your camper....

As you may know people use these to secure jack's, axes etc. to they're rigs so their pretty secure.
That's a great idea. Thanks for the link as those could be used for many other things as well.
