Just wait till the AC goes out. Half the RV has to be torn apart just to get to the AC unit, the cabinet is built around the ac after it is installed, and not with screws, but with staples, wafer biskits, and clear silicone caulk. Very poor design. In the 3 years that I have owned my 2011 Sportsman the waterheater rusted through at a weld on the tank, the converter went bad, and now the ac compressor is shot. This will be my 1 and only KZ product. All out of warrenty, so repairs are out of pocket. KZ would not want me to do a review for them on their RV's.
