Curtis Reed Report post Posted June 24, 2016 RV Comfort Coleman Mach HC Digital Thermostat. This is made specifically for RV heating/cooling systems. Has the dual speed fan switch, and comes with manual and paperwork. This is brand new never used. I have one in my travel trailer and it works great. Get rid of the terrible in accurate analog thermostat in your camper. This is one of the best/cheapest upgrades you can do on your RV. Direct wire for wire hookup. Takes 5 minutes. This will put an end to the hot/cool temp swings in your camper. $50 - Queen Creek weekends/evenings, Scottsdale/Phoenix weekdays. 480-382-0493 Share this post Link to post Share on other sites
