It can/will damage the tailgate latch? Does it allow rotopax at all in the door linked version?
LoD says you can run rotopax only on the passenger (hinge) side of the door linked units. I am not sure if you can attach the rotopax carrier arm to the driver's side in the door linked units. You might be able to, but it would definitely increase the stress on the latch which is the weak link. With the free swinging unit the bumper/frame bears all the weight.
