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.

You've already answered your own question. Change your dead battery and it'll likely work fine.
Changed the bad battery yesterday. Then check engine light came on. Returned code showing MAP fault. Didnt plug heater in last night. Engine light on this morning and had same slow turnover this morning. Cleaned the MAP sensor and ran the truck for about 10 miles. Engine light went out. Will try again in the morning without the block heater. Since MAP sensor sends info to the computer to allow it to determine airflow thus determining amount of fuel to deliver, hoping normal starting will ensue.
Turnover during starting is hovering near 200 rpm. My understanding is the engine needs to be at 200 or above to start.
