Welcome to the 'Bolt. There are a few Inianaers, Indianaites, Indianans (what you call it) here on the board.
When looking for a truck always keep in mind what you want the end product to be. If you are wanting a stock driver and do not care about new paint, V8s, independent front suspension, then look for a running and driving truck. If you are wanting a street rod, look for an uncompleted project. They can be had for cheap and usually have enough parts and spare parts to complete the project. On all trucks, look for rust in the floors of the cab, cab corners, running boards, bed sides, and fenders. Half tons have more parts available to them, so keep that in mind when you look, as it can be difficult to find certain wear parts for the larger trucks, brake drums for instance.
Others will chime in with their ideas.
