I purchased a new 2017 Greyhawk 29 MV a couple of months ago. It has one 15,000 btu air conditioner. I have the custom paint job in a dark color. The one air conditioner is totally inadequate for the hot summer days in south Louisiana. The Jayco Service manager said it was "not designed" for the south! I would suggest getting the option of 2 - 11,000 btu air conditioners if you plan on using it in 85 degree plus temperatures. I will have to address the problem before spring.
Other than the air conditioner problem we absolutely love our MH. Good quality and workmanship and the 29 MV has plenty of cabinets and counter space.
