Yes, we did quite a bit of research before deciding on colorado camper - the rear window was most definitely a selling point. Do you have a maxx air fan on yours? We will have one on ours , hoping it will help regulate the temp. Two reasons on the nvp..we were in the right place at the right time and got a great deal, and rear air was important to us...we travel with an 90lb dog and need him to be comfortable as well. This van has rear air and Colorado Camper is able to reroute it so it will still work. Got it...I'm still trying to get the whole idea of social media...once I get it going i will post a link
