Tips on Keeping Motorhome Cooler

Some good stuff I saved from another poster:

"NONE of the RV A/C units can keep a MH cool when the temps reach 90.

Instead of adding a unit you need to add things to the MH to keep the "heat out" like all the rest of us have to.

First in a Class C you have to cover the cab area from the coach area or your MH will never get cool. This is where MOST of the heat comes in thru the windshield and side windows. Also make sure the vents for your chassis heater/ac are closed before you shut the engine off.

Cover all roof vents with vent pillows. A ton of heat comes in from these plastic flimsy not sealed vent covers, and you loose a lot of air thru them too.

Park facing north or south.

Add windshield sun shades to the 'side' windows where the sun is coming in.They fit right under day/night shades, no taping, velcro necessary.

Put awning out and placed in it's lowest position. Face your MH so that the awning is on the side where the afternoon sun is.

And if you really want to get serious about seeing how cool you can keep your MH in the heat....add a de-humidifier to assist your A/C. I did and it is unbelievable what a difference it makes.

Adding these insulating items to help the A/C will drop the temps in your MH by 20 degrees."
