I'm new to this discussion board so bear with me. We are shopping for a 5th wheel and came across a 2006 Keystone Outback yesterday. It looked like good construction but strangely enough, we did not find a thermostat on any interior wall. I did find a remote control for the air conditioner and it looks like it may control the heat also but not sure. Can anyone shed some light on this remote and not have a thermostat on the wall somewhere.
