That F250 was starting to turn into a money pit.  Only had 67K on it and it had already been if for front end work, multiple CEL gremlins and not to mention rear taillights at $3500 a pop. Yes, I could have gone to some cheap aftermarket but didn't want to.

Company vehicle = their problem

1200 km to how many litres?  

How have you found it in 25 below weather?  Warm enough?  Any drafts?

Ya, but you moved from Ford to GMC....massive fail on your part. That ford will still be running problem free for years after that GMC is in the shop on a regular basis with massive service bills..... Might hit a few nerves with all the Chevy lovers on here....lol
