I would like to hear from others who have drilled drain holes in their TJ frames. I have inspected mine inside and out for rust . I don't see anything, not even surface yet and I'm in New Mexico where it is dry, not much snow and I don't think they use salt here. Still, some of the frame pictures I've seen on this site are unreal with rust damage. I have heard it both ways, it's ok to drill drain holes in the bottom, and some have said you should not because it weakens the frame. There must be some reason that Jeep did not put drains in the bottom. I would like to be able to hose out the frame inside once in a while but I don't cause I can't drain it out. What have others of you done about what seems like a very odd design weakness.
