Re: hauling SIB in the back of a truck
I haul my SIB in the bed of my short bed Ram 2500, though my boat is only 10 feet long, and probably not as wide. It's a wood floor model. It will sit flat on the bed floor as long as it is partially deflated (the wheel wells are in the way if it is fully inflated).
The boat gets loaded first, then the motor and gear. Then I chain it (loop on the motor plate), and tie a rope on it. Works great for me. The motor is probalby the difficult piece to handle since it is 72 lbs, it's a 86 Johnson 9.9.
