Next week I join the c10 ranks Hopefully!

So i am looking to buy a 67-72 c10 this next weekend with a budget of 4k. Any advice of what i should be walking away from or at that price point worth picking up. I know at that price point there will be some rust and other problems. I am new to the classic truck world. Not a practiced wrench turner but learn fast and have done some basic small projects over my short 40 yr life! Carb rebuilds, intake installs things of that nature. Just want to get a post in here and try and glean some knowledge from others with lots of experience. I am in WA state but live on the Columbia River so WA,OR are both areas i am looking in. Thanks for all reply's before hand. I know i will have to invest money in a 4k 50yr old truck. Here is the short list so far i am interested in.
I live 4 hrs from Eugene but my sister an 45 min drive so she is willing to get me more pictures since the Seller on this is not pc savy and does not know how to send more pictures. had a family member do the CL post for him.
