If you want your camping season to be more comfortable, you will need an RV thermostat. The best RV thermostat will allow your air conditioner to work flawlessly, and it will continue to do so for many years to come. And the best part is it will help you in saving your energy bills. 

But which RV thermostat to go for? In this guide, we will answer this question by providing you with our top 5 recommendations. 

Buying Guide

Here are various features to look for when buying an RV thermostat. 


This is probably the most important feature that you need to look for in an RV thermostat. If it is not easy or simple to use, you might have to deal with many headaches to operate it. You can either go for a fully automated model or the manual option. A fully automated model is a better option because you don’t need to worry about the on/off functions. The thermostat will take care of the temperature automatically.


As strange as it may sound, but looks as if your RV thermostat will matter a lot. If your RV has a modern and contemporary touch, you need a similar thermostat look. On the other hand, you need to go for a non-digital unit that looks classic for older RVs. 

Quality and performance

No matter what price you pay, you can expect that plastics are used to construct camper thermostats. There will be tiny wires inside the unit, and when we talk about quality, such a device won’t be easy to crack or break. 

Good quality thermostats do continue to run years after years without any service or maintenance. You will only have to go for the battery change if you have a unit that runs on the battery. Also, look for a good warranty and don’t go for the thermostat from a brand that doesn’t stand behind its products. 

How does an RV thermostat work?

This device can detect the internal temperature of your recreational vehicle. It will turn on the furnace if it’s too cold inside. Most thermostats can also turn on the air conditioner if it’s too hot inside. 

This device is hardwired into your air conditioner or furnace and goes right through the 12V system of your RV. There are sensors inside this device, and they detect the change in temperature and turn the appliances on and off. 

What are the different types of RV thermostats? 

There are three different types of RV thermostats. There is an analog device, a digital or an electronic device, and a programmable device. Analog units are the older devices with a sliding switch that moves according to the temperature changes. Unfortunately, this device is not accurate.

A digital camper thermostat is way more accurate, but it does work like its analog counterparts. Programmable units are the best, and they are the easiest to use. You will have to put the settings into the memory of this unit, and it will continue to work according to those settings.
