If you have a Harbor Frieght store in your area,they have a couple of different types.I bought a 5,000 lbs hand crank that we instaled on my 18 foot trailer easy, we just drilled four holes in the steel floor and bolted it in, the arm swivels out then you attach the hook and crank crank when high enough just push the motor into the trailer,works great i think i paid 179.00 for it money well spent
