72 C10 - 900 Mile Trip Preparation

[Ryan5O]

My Grandfather is that stereotypical farmer with all the old cool stuff hiding in a barn. He and my Grandmother have recently gotten that mentality to start getting rid of their things so they wont be a burden to the family after they've past. Before he could get rid of his 72 I made him an offer on the truck and will be picking it up next month. Its well taken care of and in great shape, but you never know until you get it on the road. Other than the usual wear that time wreaks on trucks, is there anything C10 specific that plagues these vehicles? My wife will be driving a second vehicle, I'll have towing coverage and will be bringing some tools along. We'll be driving the truck from Eastern MT back home to Central WA the second week of July. You guys are the ones with the experience, what do you recommend?

Thanks in Advance
