Need some opinions on a truck

[HotSauceZee]

Howdy all, I'm a new member to this forum. I signed up because I really like the look of these older Chevy's and may want to own one someday. Anyways, past myself, the real reason I have made this thread is because I need to ask y'all's opinions on an old Chevy my family has sitting out on our property. I believe it's a 1980 Custom Deluxe C30 Dually. I like the looks of it and I've been told if I want it I can have it so i figured why not? The catch is that this thing has been sitting out next to an old shop for approximately 8 years since it was last driven so I know there will be myriad of troubles with the thing. I've come to you guys so that maybe y'all could help me figure out at least some of the major things I'll need to fix. I'd like to steadily build it up to something awesome but I'm a poor college student so that'll take a looooong time. I'd love to give y'all some pics that could help y'all identify things but I didn't think to take pictures when I was down there last. :/

So what all will need to be done to this truck? I know it'll need a new battery, spark plugs, oil and fuel filters as well as new oil. The tires are all flat so those'll need to be replaced. Hopefully the rims aren't in too bad shape? The muffler will be more than gone most likely and who knows what the frame'll be up to? How about the fuel tanks? Engine?

As y'all can tell, I'm pretty inexperienced with this stuff but I think that the truck can serve as a great learning opportunity for me. So anyone have any ideas? I'd really appreciate y'all's input.
