Just had this washed for the first time in 10 years or so - maybe 15. Need to use it Christmas day to haul a few things, so wifey wanted it clean. She had errands to run this morning, so she gassed it up and ran it through the car wash. It's supposed to rain tomorrow, so it may have been a futile attempt.
'97 Z71 Silverado, bought it new, has just under 125,000 miles. There's a 5th wheel plate in the bed, spent most of it's life pulling a 20' gooseneck to and from auctions. We've sold the property, the gooseneck is gone, and I just have a 16' tandem axle car trailer to move my stuff. Front brake pads several times, rear shoes once, one water pump, one alternator, and a radiator. Other than that pretty much untouched.
As soon as we get ready to start moving, I'll run it down to my long time repair shop and have him do a complete tune-up, tranny service, front and rear differential, and transfer case fluid change. Should be good for another 125K.
