Here's what I do for my smaller 10 foot trailer. I built just a wood frame with some braces in the middle and drilled two large holes on either side in the middle, tied a rope to it and that rope will reach the end of the trailer where it stays. Now load it up normally, but then I'll back up to a tree or something heavy and stationary and take my tow strap and wrap around the stationary object and clip it the the hoop in the rope that's laying at the end of the trailer. Now simply drive forward and it'll pull it all out for you. Kinda defeats the purpose of the dump part of the trailer, but...it works for me and my non-dumping trailer. From a 15-30 minute unload to a 2-3 minute.
