on pop up campers there are stabilizers on the front and back, they drop down from the frame to the ground. why not fab. stabilizers for the back of the trailer that will come to with in 3 inches of hitting the ground. This will allow you some clearance for the ramp while keeping the back of the truck from getting to light while unloading. A stabilizer could be as simple as a piece of square tube stock welded vertically on the outside back of the frame. Then find a piece of square tube stock that will fit inside the piece that is welded on the trailer. When the longer inside piece is 3 inches off of the ground clamp it and drill a hole through both pieces for a pin. Then repeat the process with the stabilizer in the up position for traveling.
