    I'm going to look at an out of state '04 tomorrow and have asked the seller to perform the hammer test on the frame. He said that some of the undercoating flaked off when tapping on the frame but from the pics he sent the metal underneath looks okay. The hardware looks unaffected and one side of the frame looks great which leads me to believe it may have been an issue with the application of the coating. The truck spent most of its life in snowless areas with the exception of a couple of years in Alaska. Thoughts?

    Based on those pictures it doesn't look bad. However, you need to climb all over that thing to see what it's all about.

    If you end up buying get that undercoating off!

    Moisture gets between the undercoating and the frame and in most climates never dries.

    A good coating of sheep fat seems to work wonders.

    Pictures are hopeful, personal testing still required.

    As @Wyoming09 says, ditch the 'undercoating' ASAP and go with something like Fluid Film or WoolWax if you live in salt country.

    Looks pretty clean. But it's the inside that counts! Absolutely concur on FF or WW or even just oil/grease, anything to stop the rust.

    Thanks for all of the input! I ended up picking up the truck; frame was solid all around. Now to get that undercoating off...
