What engine temperature are you guys running?

A thermostat, is a cheap and easy replacement. That's where I would start. Here is something to consider:

I've changed mine multiple times, and it's always cold. Unless I'm towing heavy through town at low speeds in the summer and it's 90+ out, it never goes over 190. This is nice, except that in the winter I don't have anything but cold air out of the heater until I've been on the highway for a half hour or more. If it's less than 40 out, it'll never go over 165. I hate it. I've talked to both Dodge and Cummins, and they both assured me that it's perfectly normal and not to put a hotter thermostat in. Pisses me off.

Tried that once, buried the temp gauge pulling a load through town even though it was almost freezing out. Tried covering only part of the radiator, then a different part, wasn't able to get a combination that wouldn't overheat but would actually make the heater work like it should. Trouble is, it isn't unusual in the winter here for it to be single digits at night then 40's or even 50's during the day. Gave up.
