When we ordered our trailer I measured up the the rear door clearance for our Pajero, it needs 1100 mm from the tow bar (distance from the tow ball to the end of the door when fully open). We now have just enough room to clear the stone guard, a little short if the trailer is angled to passenger side (not usually a problem can still open the door enough to get everything). Like speewa we had trouble with the door fouling on the treg hitch, the new trailer has a lower profile hitch (oz hitch) so it clears it no worries.
