A friend of mine came up with a good idea for carrying our two 10 foot kayaks. We couldn't get them through the door, but we do have a back window that was just big enough to fit them through. We replaced the standard type window in the back of the fiver with an emergency escape type window. Now we just open the rear window, similar to raising a camper shell rear hatch, put one of the paddles under it to hold it open, and feed the kayaks through. We wrap a couple of movers blankets around them, once inside, to keep them from bumping or scratching anything. They ride nice just sitting in the floor.
Works for us.
