Not getting up to operating temp is a big red flag for fuel economy. The engine is running rich, and the transmission is probably holding lower gears to get the engine up to temp. If you have somewhere to plug in your block heater, I'd definitely put that at the top of the list (along with a gauge). You shouldn't need more than about 2 hours of pre-heat time.
