Don't you just love surprises.

OK I knew I had a little rust on the rear of my cab BUT I get the box off to put in my new gas tank and look what I find



Pretty bad indeed. BUT now comes tha hard part - do I just patch it up OR do I cut the whole area out and make a sub box in the bed.??? Tuff decisions.

thats always fun

man after seeing that it kinda makes me wonder about the frame and what not.have you checked anything else for rot?my mazda has a left side frame rail rotting pretty bad.but when i get my yota on the road im going to attempt a back half.

^^^like he said, check the frame.
rust is like an uncontrolled cancer, the earlier
you catch it the better off you are!

good reason to make it a walk threw=)

mine was rusting on both side of the cab, not as bad though. i patched both sides up pretty easily.
i would patch it up...unless you really want to do a walkthrough.

good oppertonity to do a body drop!

This one is going up !! not down.

I have checked the frame on the rear half that is exposed and all sems good so far. I will continue the inspection when I get underneath to pull the fuel tank out.

seeing stuff like this scares me as to what i will find when i start tearing my 56 chevy pickup apart.....u know, cause its only like 40 years older

That is true BUT you have to remember old chevy and gmc stuff is heavy and doesn't rust through as easily.
