The OP is in Florida. This is a bad area to utilize an Alfa unit in heat. Alfa units(motorhomes) could NOT cool the interior below 80 degrees in temps above 90 degrees. That is one reason we quit selling them after taking on the Franchise in the mid 2000's. At one point Alfa Motorhomes were the top selling Diesel for about 1 year. The reason they could not cool the motorhome was simple. They used a Basement air system(mounted in the rear under the bed) and due to the forward slideouts build in the storage area, they did not and you could not run an adequate hot air return from the front area of the motorhome to remove the hot air when the cold air was forced in. They had NO return air at all from the mid section forward. So, if you want to use these units in HOT climates, not a good idea to use one. Your customers will not be happy. They were also notorious for breaking the drivers side front slide motor/gear rack assbly. The Rack assbly was not strong enough for the motor/rack system as designed for the weight of the slide. Trade value is pennies on the dollar. Doug
