To not have a available backup system or remove it would not be my recommendation..

The factory block heater has a short 110volt cord.  Not part of the coaches electrical system.

So it could be separately powered from any source including a small gen to heat the motor.

Belt and suspenders stuff.

I replaced the block heater on our ISC about 4 years ago, when I discovered that it wasn't drawing any current...  Easy replacement and only lost about a quart of coolant.  I think I had started the engine while the heater was on, before I knew that was a bad thing.
The block heater draws about 10 amps, and the block feels warm in the morning.

If we're hooked up, and the temp is going down below 50 at night, I always run the heater overnight, although it will start when it's much colder.  Oil flows better when it's warm, and I try to be kind to the engine.
