I'm still wondering how rigs are handling the extra weight on the tire carrier and/or rear door.


Well, it is an OEM Mitsubishi product so that tells me the body is most likely built to handle the option and its resultant added weight.

Edit whups misread your question LOL.

That said, I know Carlos carries a 37x14" goodyear mudder on his door. It does pull the door top away from the body but not enough that it leaks in heavy rain or anything.
