With these guys it's the time taken to do it, depends on the shop. They are great no doubt about it, one thing I learned never piss off a mechanic or the operator that's loading you. These guys have a mile long waiting list on trucks to repair and get back on the road, yepper the good ole days of walking into the shop and hearing all the cussing going on, almost brought a tear to my eye. But I got the parts ordered and there was no smiling involved and no have a great day.
