Clete and George, both of your dumps looks good to me. You know the old saying,"whatever it takes to get the coon". I like George's tilt bed , seems like it would work great for loading, and Cleatus' looks like it would work great for unloading.
I am going to do a small modification to mine as it seems to run out of fluid after dumping several times and doesn't want to go to full cyl extension. I'm going to put a TEE in the vent hole and plug 1 side and run a hyd, line from the top of the cyl to the other side of the TEE and fill the top of the cyl with fluid. I suspect that the seals on the new cyl let a small amount of fluid by so that after it is dumped several times there is enough fluid into the top side of the cyl that will allow it to run out of the top cyl vent when the lift is down. So I'm going to use the volume as a extra resevoir. I think the plug in the TEE will also have to be a vent also as there will be more fluid going into the bottom of the cyl than will be coming out of the top when it is being dumped. I probably won't do it for a couple weeks as I'm pretty busy just now, but I'll let you know how it works then, later, Nat
