I have the mototote version....(click my two wheel photos) it fits a clas III or above hitch (square). dont have a pickup truck, but personaly I'd go with buying a ramp for your truck since you already have one, much safer. :dthumb:
I just didnt want to drop 30-40k on a new truck just to haul bike around, but when it comes time for me to get a new car...definitely will be getting a truck..now that I ride.
Two weeks ago, I was hauling my bike on the tote to the shop and when I was unloading, while releasing the rathchets, the bike leaned hard towards the rear glass of my suv and shattered it (handle hit my window).
If you decide to go with this option and dont have a hitch yet, Id go with a class 4 hitch if your truck can handle that.
