I was thinking about ramps that have are secured to the trailer or are part of the tailgate. The design Xfaxman showed would work, as it is close to what my Big Tex has. My other trailer has 3" channel with angle iron ramps and it has legs. The trick is to make the legs touch the ground when a heavy load rolls up on it, as the rear of the trailer squats, but before the ramps actually bend. The way we determined this was by using blocks under the ramps and rolling the backhoe up on it till the the trailer squated and the load was partially supported by the center legs. With removable ramps, it can probably still be done, using a leg similar to Xfaxman's picture. Always determine the length or height of the leg when the dovetail or rear of trailer is under a load, not sitting in the shop being welded up. Another way is to use two short pipes welded to the sides of each of the ramp and have a leg that drops into that pipe with a series of holes to allow for todays position and load. You would still need to leave the leg higher off the ground, so that when the load is only partially supported by the center leg. We are only trying to prevent bending of the ramp and back end of the trailer with this leg.I’ve tried that when I was trying not to bend my junky car hauler ramps. The problem is the trailer lowers as you back off of it and the leg holds the ramp up and it falls off the holder. The other problem as you already mentioned is the ground isn’t always level. Getting the height to work would be about impossible. The 3rd problem is it’s a dump trailer and the ramps half to be flat to store properly.
For people without welding or fab skills, a short piece of railroad crosstie put under each ramp to take up some of the weight might do all the need. Just remember to put it to where the ramp will be, not where it is at when you drop your ramps.(lighter loads, lighter trailers all change where you put it), so just remember the leg is just there to help support the ramp under max load. I used a 6x6x14 inch block of wood for years, till someone borrowed one out of the truck at a jobsite and I had to find wood scraps to use so I could load the tractor! A lot of variance in the size of block is due to height of the rear of trailer, length of ramps and the weight capacity of the rear portion of the trailer.(how much it squats when being loaded.
