New to site, got my truck, i have questions

[sameyeam]

Hey guys, new to the site, i just picked up a 1972 Chev K20, small block, automatic, with a holmes 440 wrecker unit on it. My grandpa actually ordered it new and through some searching we were able to acquire it again. I am happy to have a site like this to help me along with this new project, so thanks ahead of time for your advise and answers to questions im sure i will have.

Now this truck was a northern wisconsin truck its whole life, and needless to say she's got some rot, i am going to attempt to post some pictures and i am wondering if this sort of this is worth fixing or is it fighting a losing battle and i should start the search for a new cab?
