The scoop (everything I know) is as follows. truck has 190k miles, apparently the dealership is sitting on receipts for at least the following:
s012 float.......
carb kit........
exhaust pipe ga.....
clutch master cyl....... 4/06
brk bearing...4/06
bx thermst.....5/06
They sent me pics of the exterior, interior, and underside. Honestly, this thing's clean enough that I'm not altogether worried. I don't know about a lift, but the pic below makes me thing my first spend will be on some real shackles.
I'm in New York, which has made the whole exercise much more difficult, but I think I got a nice truck. It'll never be totally trailed out (not enough money and not a lot of time for expeditions), but I'm looking forward to some new bumpers, probably wire some nice speakers, and see what happens from there.
I called the place about the engine knock - they said they just put some fresh gas in and it was fine, and that they stand behind the "runs like new, drives like new" statement in the ad. It wasn't an enormous financial decision, I'm using a credit card, and I know some good lawyers, so I'm not altogether worried. That said, if anyone would like to cruise over and start her up and give me an opinion, I'd really appreciate it.
