Any feedback on the Coleman Mach 9430-337 RV Thermostat

So I came across this thermostat and wondered if anyone had used it to upgrade their analog thermostat. It's interesting to me because I have limited width where my current thermostat mounts. Here are some pictures of the unit and the documentation. It's available in both black and white. Best price I found was on Ebay for $39.99.

So I got one of these and it is a simple replacement for the analog Coleman Mach thermostat that came with my trailer. Hardest part of this project is going to be covering up the holes from the original thermostat. Here is a picture of it temporarily hooked up to confirm that it works.

Would you think the factory could maybe use a hole saw or something.Looks like the chiseled the hole out with a screw driver!

The digital Coleman is a bit wider that the stock analog. I had a width issue also. The coleman sticks out beyoud the door trim about an 1/8".

How does it work? Are you able to control furnace/AC/fan speed?

Works great so far. It has the same amount of control as the original. You scroll through the settings by pressing the bottom button. Temperature adjusts via the up/down buttons.

In my opinion, it looks like they did all of the woodwork with that chisel.
