I bought a 1996 nomad a few months ago when my job transferred to another city. I have lurked around a lot before this post and there is some great info here. Anyway here is my problem. The other day I noticed the door was dragging when it is closed and decided to check it out. I pulled the bottom aluminum piece of the door and found a bunch of rotted wood. So how easy is it to fix this? Can I do it with out having to take the door completely off? Am I correct to guess this was caused by a water leak somewhere? Where could that leak be? Any help would be great
