Trade it for what? ZR2 with a baby duramax?

Oh yea! I know I've only got 2,500 miles on mine but so far so good.

Update on my 24: See attached for the two main pages on my repair order... They basically said the failure was top down - broken valve spring led to dropped valve led to piston scoring led to spun rod bearing. My hunch (based on known 6.2 issues) is the other way round - bottom up failure. They had the truck six weeks and change to fix it.

Got the truck back three days ago and coolant temps would max out after three minutes or so in operation (while oil temps remained fine). Took it back this morning. Diagnosis was air in the coolant system which was purged and refilled. Seemed OK on the 10 miles home - we'll see...
