Welcome to the Forum and enjoy your new Montana. Cooling your unit can be hard to do. As stated before the dark colored exterior walls don’t help us. I will say having the double Paine windows help out a little bit and being in any shade makes a big difference. It is much harder to bring the temperature down compared to maintaining it. I will sometimes also bring the temperature down lower at nighttime or early morning as I know my inside temperature will go up with the heat gain of the day. I really wish that they could make a better insulated unit even if the weight increased marginally.
