That is a great set-up. I really would like to buy a Servonaut unit sometime for my own truck. I like the trailer you have too. That's really cool how the tarp works. As for the hydraulics being jumpy on the way down, I'd guess that maybe the cylinder is binding up a bit. You've really only got gravity helping to collapse the stages. Is that a Wedico pump and telescoping cylinder? I think Ralph (the trailer builder) always adds one more stage to the Wedico cylinders, for more lift. I'm not sure if he's a regular member here, but I think he is. Maybe ask him for some advice. Or maybe he'd be willing to take a look at the cylinder and get it working better for you.
