My water pump blew on my 6.7 around 4pm on Thursday. Called around until I got to ROKS. Yes, they could take it and yes, they could get on it the next day. Say what?!?! That was unusual to hear. Though they officially lose at 5:30p, there was still someone there at 6p when I got pulled into the yard. I called Friday morning to verify all was well. Was informed they were rolling the truck into the shop and the part was being delivered. Called back at 5pm to get update and they confirmed that the plan was still to have it done that day. 5:45p: called them back and my truck was out on a test drive. Got a call at 6p that it was ready for pickup! Crazy!! 24 hrs from when I dropped it off to when I got it back. Was not thinking that was possible in this day and age. Not a guarantee that they can do it for you in that time frame, but it definitely worked for me. I'll be back to them again. Hopefully, not too soon. ;-)
