Hi folks. We purchased our first diesel truck in February. A 2014 Sierra 3500 HD. I've been reading a lot about diesel trucks as it pertains to pulling a trailer, but what I haven't found is info...
Not sure if it was mentioned, but you should carry a spare fuel filter. I always carry a spare and just this past week, the "water in fuel light" came on in my truck for the first time since I've owned the truck (8 years). I filled up at a station I normally don't use and think they may have had bad diesel.
