Just paid 60 bucks to a tow truck guy who had to boost me
Ran the truck yesterday for half an hour - everything was good. Shut down for the night, used the bunk heater to sleep, and then the temp went down to -2F or -18 C all of sudden. The starter was barely turning. The tow truck stayed hooked to the battery for 30 minutes, and I was able to start the engine. Whew ... thank goodness I replaced all 4 batteries last winter. So now I'm running the engine till morning for sure. My question is: if I don't want to idle for heat, at what temperature I MUST idle anyway so that the truck can be usable in the morning? Thx!
