Keeping Diesel Engine Warm
My dodge dually Cummins engine is very hard to start when cold. At home or camping with hookups I can plug in the block heater but what can be done when boondocking.

It's not your grid heaters - guaranteed.
The K&N issue is not even debateable. It's a documented problem that Dodge and Cummins have written TSB's for. And yes, many have indeed had a "problem" with excessive blow-by and warranty's were cancelled when the intakes were found to be dirty form K&N or other washable filters. (The TSB specifically mentions K&N).
In my own case, I used one for a short time until I read about "dusting". Sure enough, when I wiped the intake tube with a white paper towel there was dirt.
If you want a better breathing filter for that era of truck, use the 3" Fleetguard replacement for the 6.7 (AF27684). It breaths BETTER than the K&N and stops more dirt.
BTW, it was in the 20's here this AM when I started my truck. I intentionally hit the starter before the grids and it fired after the third cylinder came up.
Until you get well into the negative temps, the grids are mostly for emmissions.
