We usually transport our tandem using an ATOC Tandem Topper on our Subaru Outback but we also have a GMC pickup that I would like to use to carry the tandem. I tried a Yakima BedHead fork mount, but even with the front wheel off and the fork mounted up on the front bedrail the tailgate won't close. I know that I can get in diagonally, but I would prefer to find a way to carry it straight front-to-back so that I have maximum use of the pickup bed for other stuff. Does anyone use crossbars that are above the bed to carry their bikes? Does anyone have pickup truck solutions that don't require drilling holes in the truck bed? Thanks.
