So in the case that you intend to head out with your RV in the upcoming days and want to optimize your experience, you must ask one question: Do I have the best RV thermostat?

With an appropriate thermostat around, you could apply changes to temperature inside your vehicle as you see fit and maximize the overall level of comfort.

Reviews on The Best Thermostats For RVs

Once it comes to the best RV thermostat, RVers tend to be at odds with each other but if you wish to get your money’s worth, remember to give the following models a look.

1. Honeywell TH5110D1006 – Best Of The Best

Best RV Thermostats: Controlling The Temperature Inside Your RV! 1
Check prices and reviews

Specifications And Characteristics:

  • Dimensions: 1.3 x 4.5 x 3.4 Inches 
  • Weight: 0.4 Pound
  • Back lighting 
  • Digital display 
  • Push-button 

Why This Is The Best: 

Being both light and compact, TH5110D1006 of Honeywell could be put to good use in all kinds of settings. With an easy-to-see digital display, the Honeywell thermostat allows RVers to grasp the current temperature at a glance. In addition, the display of TH5110D1006 incorporates back lighting so people could check out readings in low light conditions. As a result, those that often have to travel at night and don’t want to deal with obscure readings think of Honeywell TH5110D1006 as the best RV thermostat. 

In use, the robust push-button control interface of the thermostat made by Honeywell means adjusting the interior temperature is a walk in the park. With TH5110D1006 by your side, you would be able to set the temperature inside your rig to your liking. As for power, TH5110D1006 of Honeywell is designed with two options: batteries and hardwire. The battery compartment of the thermostat from Honeywell proves to be highly accessible, thus, it’s a breeze to swap batteries in times of need.

Regarding post-purchase support, Honeywell backs its RV digital thermostat with a five-year warranty. Hence, if your TH5110D1006 fails due to defects, you could claim a free replacement.

This is an upgrade to my Flagstaff camper. It was very easy to replace and it is maintaining an even temperature in the rig. As a result, it is using less propane than the inaccurate Coleman-Mach that came as OE. As a bonus, it will operate the air and heat automatically, switching from one to the other as outside temperatures dictate. As a mod for a camper, you can only have one fan speed without adding an additional switch, however I kept the high fan and taped off the low fan wire and haven’t missed a thing. There are videos that can help you through the modification if you need the assist. This is less expensive than the OE replacements and a far superior product.

Why It’s An Editor’s Choice:

Despite its rather plain appearance, Dometic 3106995.032 is still a solid thermostat that never fails to match the needs of RVers. Possessing dual-control, 3106995.032 could manipulate cooling as well as the heating appliances of recreational vehicles. Because of that, with the thermostat from Dometic, you don’t have to move all over your rig to operate the furnace and air conditioner. Moreover, the control interface of 3106995.032 of Dometic features convenient sliders so you should have no trouble applying adjustments to temperature.

Besides that, the setup process of 3106995 is straightforward too and only takes minutes to complete. Needless to say, RVers that need to replace broken thermostats in a hurry usually deem Dometic 3106995.032 to be the best RV thermostat in the market.

I ordered this thermostat to replace an identical thermostat in my 2005 Keystone Sprinter. The original device would start the furnace only if set at 90 degrees. I needed two screwdrivers: one to remove the old device from the wall, and another to loosen the screws that secure the wires in the connectors. I taped the wiring diagram to the wall and donned my headlamp. Less than 10 minutes later, I had the new thermostat mounted to the wall and the wires connected. Now the furnace starts and stops and cycles correctly. It was a quick, easy repair that didn’t require a service call from a very expensive RV service.

3. Coleman 7330G3351 – Editor’s Choice

Coleman 7330G3351

Specifications And Characteristics:

  • Dimensions: 4.6 x 3.7 x 5.0 Inches

  • High and low speed control 
  • Single-stage 
  • Auto/on 

Why It’s An Editor’s Choice:

With a user-oriented design, Coleman 7330G3351 permits fast and effortless adjustments to temperature in the interior of recreational vehicles. The thermostat made by Coleman is capable of controlling pretty much every system used by RVers to regulate temperature from air conditioners to heat pumps. After you set your temperature, 7330G3351 would automatically activate heating and cooling appliances to keep temperature from going above or dropping below the set level. So if you add 7330G3351 of Coleman to your RV, you could manage temperature inside your rig as you like.

Since 7330G3351 is an analog model, it boasts uncomplicated installation and no-nonsense maintenance requirements. Naturally, the Coleman thermostat is held in high esteem by RVing enthusiasts that wish more time on enjoying themselves and less time struggling with equipment. It’s worth pointing out that 7330G3351 of Coleman is hardwired directly into the power system of recreational vehicles too. If you opt to purchase 7330G3351, you don’t have to bother with battery swaps in the course of operation. 

Though Coleman 7330G3351 indeed costs a bit more than many of its contemporaries on the market nowadays, the values it provides justify its price tag. The thermostat for RV of Coleman is even backed with a two-year manufacturer warranty. To plenty of cautious owners of recreational vehicles that seek a sound insurance policy, 7330G3351 is the best RV thermostat

This is a 12 volt, dual function (a/c and furnace) control unit made for RVs that have Coleman-Mach thermostats. I live in a 2000/01 Arctic Fox 26X travel trailer and recently replaced the furnace, but the thermostat wasn’t working correctly before I replaced the furnace and has not worked correctly with the new furnace (which had a bad fan but was old so I replaced the entire thing since cost to repair was so high). With the old Coleman-Mach, the original thermostat, it would not turn off the furnace sometimes when the set temperature was reached. This was the only reasonable manual thermostat and I was told that if you have a Coleman-Mach, you MUST use a Coleman-Mach replacement or face rewiring issues etc. This one comes with excellent instructions, but essentially was 6 colored wires which were almost the same as the old. Backplate used same screw holes as the old one. Vendor sent it out immediately and it is working correctly and I am very happy. This should work on most older units and if you order here, it is a lot cheaper than ordering from the RV companies, most of whom don’e even carry this thermostat. I considered buying a second one just in case, but hopefully I won’t be living in this trailer such a long time that this one will fail! Good deal!
