1. Relocate your RV or change the orientation

If you're camping in hot spots (like somewhere in Arizona), it's worth checking which side your RV is facing. The RV windshield shouldn't be facing east or south. The best decision is to choose north or slightly northwest if there isn't much sun in those spots. The goal is to keep RV cool and avoid your rig facing direct sunlight for most of the day.

Alternatively, you can find the location where the trees cover the western side of your rig and use the awning to cover the parts of your van that will still stay under the direct sun.

You can also check the local weather conditions and open the windows when it's windy to get some fresh air inside your RV and cool it down.

2. Install Roof Vent Covers for Better Air Circulation

One of the best RV air conditioning tips is to install roof vent covers with a built-in fan. The fan, which plugs directly into a power source, will help pull air through the vents and push it into your RV. During warm days when you're parked outside at an event or in a campground, these roof vent covers will keep your RV cooler.

Downside: this cooling method requires a power supply for the built-in fan.

3. Use a Portable A/C

If you're planning on staying in your RV for a few days, make sure you know in advance how long you'll be parked before you turn off the engine. If that time is approaching or has already arrived, the best way to keep your camper cooler is to invest in a portable A/C unit.

You can move them around efficiently, and they will serve you during several years of constant use with proper maintenance. However, you must size the air conditioner correctly; otherwise, you'll end up wasting energy.

Downside: some portable ACs are expensive, and it can be a waste of money if you only use them a few days per year.

Another alternative that is energy-saving and efficient is to cool your personal space in the RV with a portable air cooler. The best parts about portable air coolers are their price, size, user-friendliness, and the fact that they cover all the key air conditioning functions. To check their models and prices, visit the Evapolar shop.

4. Use Shades to Prevent Heat Gain

One more among the RV cooling tips is adding shades or covering windows with curtains or blinds. These measures reduce heat gain and keep the excess light out, which is a nice perk if you stay in an area for an extended time.

Before going on a trip, always check whether your curtains are in good working order and create a thick shade for your camper. You can improve the natural cooling system by adding an awning, extra blankets, and parking your RV under the tree or in a natural shade.

5. Clean Your A/C Filters

You can do another thing to keep a trailer cool in summer. Start by simply cleaning out all the dirt and grime that can clog up your air conditioner. Dirt acts as an insulator, which keeps heat in rather than out. Not to mention that it can negatively impact your AC device's functioning and lifespan.

Most RVs come with a built-in filter that can be easily removed for cleaning and readjusted back into place. It's worth washing the dirt out once a week or checking the filters before a long trip to timely remove the broken ones.

6. Swap Incandescent Light Bulbs for LED Bulbs

LED bulbs heat up less, and they can shave a few degrees off your cooling bill. Even though they are more expensive up front, they'll save you money in the long run. LED bulbs use way less electricity — in some cases half as much as incandescent light bulbs.

By picking LED bulbs, you will keep your RV cooler and save money on electricity. Of course, the same arguments apply to turning off the television and other electronics you usually use inside your RV.

7. Try Alfresco Cooking

In addition to taking active measures to insulate RV for summer, you can plan some energy-saving and RV-cooling methods in advance.

For example, choose food that doesn't need a stove or an oven for cooking. If you still want to do some grilling inside your RV, choose alfresco-style grilling recipes and cook on inexpensive portable cooktops instead.

To avoid overheating the grill, remember to properly clean it before and after use. Also, use paper towels when cleaning them afterward; it will save time and water and avoid having residue from dish soap on surfaces where food might come in contact later. Finally, turn off the grill as soon as possible to let it cool outside your camper.

8. Close Windows in the Morning

This small yet efficient trick on how to cool RV in summer is a working solution to find a compromise between light and heat. First, try closing your windows at dawn so that you keep the cool air inside — it is more efficient than exposing the insides of your RV to the sun all day. Then, you can open the windows again close to sunset time.

It may seem counterintuitive at first, but using blankets or sheets and towels will help you save money on air conditioning. For example, instead of blasting AC when it's 100 degrees outside, try rolling up some blankets around doors and windows that are exposed to sunlight. This will prevent some of that heat from sneaking into your trailer. You can also try placing reflective tarps outside of windows, especially those facing southwest.
