We are planning on a week long camping trip in warm weather (average high of 100), and are looking at options to help with the temps inside of our 2001 Coleman Santa Fe. I was exploring the option of putting reflectix in the windows to help (we already have popup gizmos on the bunks). Since we don’t have AC, I started wondering if the reflectix would make it worse since there would be no airflow with the windows blocked. Then I thought about maybe a hybrid option, reflectix in the bunk windows, while leaving the main area windows open for airflow, or possibly waiting until we get to the camp site and seeing what part of the camper gets the most sun and only putting reflectix up in that area, while leaving all of the other windows open. Any suggestions?
