Like a lot of people our travel plans have been preempted by the pandemic. In our case, we had already decided to shorten our travel adventure this year as we are serving as interim pastor at Houston’s Southwest Church of the Nazarene.
And, not that this will come as a surprise to you, summers in Texas are hot! In our case, we are near the Gulf Coast, so not only is it hot but it is humid too. Not a fun mix. Not only that, but there’s no shade.
Our motorhome has two air conditioners. The bedroom a/c does a good job of keeping things cool. The living room unit, though, struggles to keep up. We’ve made six adjustments that make a big difference.
- Of course, we keep the front window curtains drawn. Not only that, but we have giant sunshades (similar to what people use in their cars) for these windows. We certainly miss the view out of our big “picture window” but this is the number one thing that keeps things comfortable in our living room.
- It probably goes without saying, but I keep an eye on the air conditioner filters. Running as much as the units are, the filters need cleaning a couple of times a month.
- Another big improvement is adding Reflectix to several windows. This is a heat reflecting insulation that is cut to fit. We have put this product on our west facing windows as well as on other seldom used windows.
- The next thing we have done is install curtains the width of the rig behind the driver’s/passenger’s seats, creating a sort of vestibule. This keeps the cool air from the a/c concentrated in our living room and kitchen and helps trap the warm air from opening the front door in the front of the rig. There’s around a 5 degree difference between the driving area and the living room.
- We are running a couple of electric fans that keep the air moving. One of the fans is an oscillating tower that makes a nice difference.
- Finally, as long as the hot wind isn’t blowing too hard, in the afternoons we leave the awning extended on the curb side of the rig. This shades the west side of the motorhome and keeps the walls from heating up.
We know that the best RV summer solution is moving to a cooler spot. However, there are times when that isn’t possible and “all the above” does help us stay comfortable.
So what are your tips for weathering summer heat and humidity in a RV?
