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.

And there is your problem. K&N is the absolute worst air filter there is. Even lightly over oiling it will kill your grid heater in a hurry. Not to mention loss of fuel economy and allowing more dirt into the motor. Your just asking for problems. Take it out, go buy a quality paper filter, clean the grid heater and see what happens.
BTW, I would dump the K&N. They are notoriously bad on turbo diesels and may actually be the problem. The oil in them fouls the MAP sensor so I would get some sensor cleaner and spray said sensor down.
Ditto on both of the above.
Does it crank over fast and just not start, or does it crank slower like the batteries have low voltage?
