My Keystone has standoffs (4") on the top of the ramp and a steel plate that flips over to the ground makes the angle better and the plate makes a smooth transition from the ground. That mod would be easy. You could probably get them from Keystone. Had an Rvision once that was set up the same and the prior owner hauled his HD bagger in it. Drove right in. That is the safest, simplest solution I know of. 4 standoffs mounted to the top on gate and a hinged plate that flips onto the ground. No big deal. Have the wife load it so you don't get hurt. LOL.
