I can't answer the question you ask but might have a solution to the parking problem at home. back the trailer in until the Jacks are close to hitting and then place a couple of 2x8s behind the rear wheels and see if this doesn't rise the rear enough to stop the dragging. Doesn't solve the problem of the placement of the jacks but would eliminate having to remove them to park at your house. Let the forum know what the final result is.
