You can always mount a 12volt removeable winch to the front, or even the rear, add a pulley, plug it in, and watch it load itself. Poerboats aren't the only ones to use this method to load and unload heavy things to your vehicle or trailer. I use one to store my kayak on the roof of my garage. I actually bought two and I still have one left if you decide to go that route I could sell it.
PM me if your interested.
