2009 Coachmen Prism Heat problem

We recently purchased a used 2009 Coachmen Prism M 230 and on our first trip we had a problem as follows: When riding with the cab windows partially or all the way open, heat builds up behind the seats and on the step up wall leading into the coach. We found it would stop by closing the windows (not acceptable in cool weather) or turning on the AC (consumes extra fuel when it is not necessary in cool weather)
Has anyone had this problem?

to paceb,im unsure of exactly what it is thats causing the heating problem,however its common knowledge that most vehicles of any type have heat spots somewhere in the vehicle,the most common causes are poor insulation around windows and doors,ive driven a truck for 35 years and this is a common problem in class 8 trucks,i know you have seen the circulation fans in vehicles,this might be worth trying as the most inexpensive soulution to your problem,if that doesnt work,then try the next possible solution,until you come up with a favorabe answer,hope this helps

Thanks for your information but this is more than a hot spot. There is quite a bit of air flow and it is very hot air. I just thought someone who had a Prism or some other Class C built on a Sprinter Chassis might have had the same type problem and was able to find a fix.
