Looking at an 03 1500

[jman340]

Hello,
I'm looking at an 03 1500 work truck that has a 4.3 in it. I've had an older blazer and an s10 with that motor, but not a full size. Before I make the deal, is there anything I should look at? Any common problem areas? It has about 80xxx miles on it. The owner had aftermarket power windows and locks installed which I know may be a problem, and need to be replaced. I'd prefer the V8, but the deal is pretty good on this. This will be used for daily commute and hauling stuff for home improvements from time to time.
