That's a 10th of our delivering fleet. Let me say that our ctr mechanic is GREAT, but......... Since this truck swap happened, this has been the norm. At least 1 b/d a week! The PTB decided to keep all make & models in 1 area (sounds good on paper); so we got all the junk (spares from other ctrs). The mechanic wants to quit & mgt rarely lets him work OT. I wish someone high up the food chain would be held accountable for this major FUBAR.
