I built this last winter out of 2" x 2" sq. tubing, casters from Menards and a 1000 lbs. 110V winch I got for $12 at a swap meet. Its 4' X 2' with telescoping legs currently at the tallest position. It worked better than I would have guessed. I added a hold chain to take stress off the winch. Loaded a 383 and a 440 for the swap meet tomorrow in less than ten minutes this morning. With a three foot run the 383 and 440 went right up the ramp.
