Performed the replacement of my analog thermostat to the Coleman 8330-386 this evening, quick and simple and the mounting holes on the new thermostat line up with the ones that were there for the analog one. And yes I can confirm it displays room temp. In order to help with the accuracy of temp reading I did what somebody suggested and filled the hole in the wall that the wiring comes through with insulation. That way the thermostat wont be fooled by trapped heat or cold in the wall thereby giving it a false reading.
What confused me though is that I had disconnected my battery prior to doing the install, yet when I was finished wiring it up, it immediately showed the room temp. I wasn't expecting that to happen till I reconnected the battery? Whats up with that? It doesn't have a backup battery on it.
