As I stated earlier, there was a temp that they recommend you should use your block heater to warm the engine. I did a search and found an article with some good info. It discusses temps, grid heaters and idling in the cold.
A question that often comes up is why does my volt meter drop to nothing and then come back several times when starting the engine. This article discusses the affects of the grid heater on battery voltage.
It's a good article for a newbie:
Cold Weather starting.
Great link Don. I agree completely with your article. Even the big puff of black smoke when it fired up. It happened to me in Pecos, N.M where the temperature had dropped to about zero. I did not plug in to shore power and let the coach just set for about a week at low temp. It wanted to start, but would run for a few seconds and then die. Until it fired up with a big puff of black smoke. I thought at first I had blown the engine up when it fired up. LOL! Since then I plug in when temperatures get that cold if there is shore power available. I have never added anything in the fuel tank, but your article about Karosene makes a lot of sense.
