AT -14 I would like to have a block heater as well. But with the newer diesels and as long as your fuel is the proper blend or properly treated I would expect them to start in most cases. I use my block heater at home if it will get under freezing not for ease of start but convenience for me.
My old mechanical 5.9 Cummins would start without a heater (and without the heater grid Rams used) down to -15 with no trouble. When I drove shuttle buses, we had more buses than heater plugs...they deliberately DIDN'T plug in the ones with Cummins engines, because everyone knew they'd start! (Some of the 7.3's, many with 150,000+ miles and 8-15,000 hours...not so much.)
