Real RVers. Real trips.In their own words.

Pre-cooling
We have a 1.5 hour drive from home to the campground. When we would get there, it could be as hot as 110° inside the camper… To be able to turn the temp down to get it cooling before leaving home has been the best investment I’ve made for my RV.

Easy install
Best investment I have made. Easy install. It’s nice to have the pet monitoring feature.

We bought our thermostat the first day of the show. I installed it on Friday and it is working great. I highly recommend this product.

Pet safety
