My New GMC 2017 Sierra 2500HD Denali

[CapnDean]

My 2006 GMC Sierra 2500HD rolled over 200K miles.  I got the fever and BAM.   I am going to  miss the EFI Live programming and fuel economy it provided.  I did not have to fool with regen or DEF either.  BUt on the FLIP sie...Holy Moses this rascal has sooo much technology.  I am overwhelmed.

 

I do need to order a set of leveling keys if anyone has a recommendation for the best ones.  I would also like to know how to tell how much DEF I have aboard well before it gets below 30% - - anybody know how to do that?
