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.

Describe cold, 40, 30, 0 or colder. Many times I don’t even wait for the wait to start light to go out, just crank. With full heater grid cycle starts right up!
Check out your heater grid, also how many miles!
