Yes...right now I'm not heating the coolant in the radiator (or the oil in the pan) and that's part of the problem. Big drop in temp as soon as the engine starts. I've considered installing an auxiliary electric water pump to circulate water when the block heater is on. This way I could pre warm the cab without the engine running. (Pumps are cheap) If I can't find a stronger block heater I'll probably install a tank type heater.

And again I usually don't have 3+ hours to leave it plugged in. I want it warm in an hour, hot in two. I don't work on a normal schedule, I don't know when I'm going to leave. I can't use a timer.

Yes, I know I don't NEED it. Nobody in Oregon needs a block heater. I don't need leather seats either. But I have them.
