sometimes . i wish id a traded my 13 superduty on a new 15 superduty .instead of the 2015 denali hd .. i just hated those dame doors that looked like there dented by the door handles , it drove me nuts .. nuts .. nuts.. love the truck other than that .. congrats

Like my 6.4. Supposedly the bottom ends are more stout than the 6.7's.

As long as your deleted I don't see any concerns on the 6.4. That being said the original batteries in my 7.3 lasted 12 years including 7 New Hampshire winters and my 6.4 batteries **** the bed on me Monday night. That was an aggitation

yes i agree the 6.4 must be deleted . the regens kill that motor . the motor that actually makes oil .

Traded a 7.3 dually for a new ram cummins about a year ago... the new motors are beasts...

Congrats...from a duramax owner. The 3/4 ton and 1 ton markets are well served by the big 3- wonder how long Toybota is going to wait to enter that market.....

Cold doesn't damage batteries, heat does. You won't actually see the failure until the temperature drops and there is more demand put on the batteries.

I agree with eveything you said on the 6.4. If you are willing to delete they are the best bargain out there for a used diesel.

I am not sure i agree with cold not killing batts....
