2000$ seems pretty steep for a big truck. If it was in that good of shape Id think maybe half that. And I like the big trucks, but that just seems like way to much. Take it for a spin around the block and see what you think.
And expect it to need at least another 500$ just to keep it safe on the road, brakes, tires, tuneup, etc... Ive never bought a vehicle that I immediately didnt have to put money back into. But then again I see people drive stuff that should have been condemned...
