I've had this Jeep for seven years now.  Its been in CA with me for five of those.  I just found acorns from NJ in the frame.

 Lets look past the fact that the rear 6-inches of frame are shot... I thought from a leaking gas tank for years... turns out some damn rodent using the Jeep to store acorns in the frame didn't help.

Since I've had it, its not sat for long enough to become a squirrel's winter feast repository, and the guy I got it from was using it as a daily driver... until the day I bought it from him.

Most of my Jeeps that the frames rot out from under are because of mud and salt... not acorns and salt.  I mean, WTH?
