Hey man thanks for the props on my truck. I dunno what the weight is. I do know that if you are looking into it, only get a 4 cylinder base model. Goes an extra day between fill ups. I have one that is a 6 cyl and other is a 4 cyl. 4 cyl rocks. Not sure about added weight with 36 . I dont think it would be a great idea. Maybe overload springs would be a good add-on for that set up. I love these trucks. We will never try anything else.
