SkeeInAn89

I've got a bright red '89 K2500 that's almost completely, if not 100%, stock. It's been in the family since it was new, and it's now mine. I've got a new coat of paint on it (it looks nice!) but now that I've got a steady job, I wanna make it look BA. I'm going to try and get it pretty off-roadable as theres some irresistible trails not too far from where I live. Whad'yall think would be some good things to do to her?
