Re: gas mileage
I just bought my 85 K10 for $3,000. It has 160,000 on it, a 4" lift, aluminum wheels, 33x11.5 muds (which I replaced with AT's) and newer shocks. I have replaced the seat, dash, windshield, exhaust and misc. trim and am still under $4,000. It will need a new engine in a few years, but small blocks are cheap.
They are out there, it took several months to find mine. If I use the egg under the foot mentality I get 14 MPG. I could pay for a lot of gas at this rate vrs a truck payment. Also the insurance is much cheaper than my wife's 99 Tahoe.
I do have a really nice Nissan King Cab 720, no transmission, but all of the goodies for $500. But trust me chevy's are far superior!
