- Keep the RV in a cool place. For when you are stopped, reflective insulators for the windows are essential and you can also opt for exterior insulators, which cover the vehicle from the outside and do not allow heat to enter the RV. The interiors can be bought by the meter and can be made to measure with a little skill to sew.
To prevent the RV from overheating prematurely, try not to go out in the extreme heat of midday. On these dates, it is difficult to avoid traffic jams, but if you leave first thing in the morning and preferably on a Tuesday or Wednesday, you will find less hassle on the road and it will take less time to reach your destination.
Perhaps the most important thing is to consider where to park at night and to think about the place that will have the most shade in the morning.
- Ventilate: When starting the trip, ventilate the RV by opening the windows and when the climate control is cold, close the windows and turn the air to 25 degrees. During the journey, he renews the air in the RV from time to time with the windows open. Covering the seats with a towel or sarong will help us not to burn our legs and to be cooler.
- Better not to refuel when it is too hot outside: Try not to fill the tank to the top or put gasoline in hot hours, the fuel expands with high temperatures. It is also not recommended to clean the RV in the full sun using cleaning products because they dry instantly and can damage the surfaces.

- Let the engine cool: The more time that passes between you turning off the engine and going to bed, the better, in two hours the RV has had time to cool down. Open all the windows of the RV and air it, the fewer things you have piled up, the less overwhelming you will have, so you can also collect a little.
- Tricks for the bed: The sheets and pyjamas have to be cotton to facilitate perspiration and before going to bed, you can put them in the refrigerator of the RV inside a plastic bag.

Another grandmother’s method that will free us from some heat in the RV is to hang wet sheets on the windows so that the air that enters will refresh the environment a bit. From the outside, to prevent the heat from entering the RV, it is best to park on fresh grass, but if this is not possible, you can sprinkle some water around the RV after the sun goes down. It is a good idea to cool the environment and that the ground does not give off so much heat.
