We bought a 2004 See Ya new and really liked it. While parked in South Texas (Pharr), our daughter came to see us. She has Multiple Schlerosis so is sensetive to heat. Faced with June temperatures at or approching triple digits, I put a soaker hose on the roof to use as an evaporative cooler while she was with us. It wasn't needed. The dual basement heat pumps kept the coach comfortably cool, even for her. We had the usual "fix it" issues that one normally has with a new coach, but no problems at all with the heat pumps.
