Hi, I searched but could not find a definate answer maybe someone can help. I know it runs off a timer and a remote but my problem is that i work for the railroad and do not go to work at the same time. It's not a problem at home (plugged in) but at work it sits sometimes for 2 days with nowhere to plug in and it is a pain to get started. Cab warmth is not a issue for me but the cold starts have me feeling i am removing 1000's of miles of my engines life each time i start it. Question is would it be worth the $$$ or if not i'm putting my gasser 87 4runner on the road to use next winter. Thanks in advance for any help.
