Oh, quick question on those GM trucks if you can recall - how many of them had 5.3L V8s, and how many had engine failures? (Not making a point in context here, actually just a bit curious as to how the CSK issue played out in a fleet like yours.)
I don't know; I would have to go pull the sheets. They were the V8 that comes with the Z71 package --- albeit the Z71 package w/out the fancy graphics (e.g., skid plate, etc.)
5.3 sounds right.
They were an OK vehicle --- just had stupid things that would break --- door locks, A/C, whatever --- but they consistently had goofy issues that would keep a few in the shop at any one time.
The seats were a big complaints. Roughnecks are not small men, in general, and the seats sagged and looked/felt like hell in 3 months.
