While I no longer have a Keystone RV when I ordered my Alfa I specified 2 15,000 BTU ac's ducked during the day I use the front one and at night the rear one. I am a Snowbird in SW Florida for 4+ months. My previous RV was Cougar 318 which maxed out at 12,000 lb and towed with a 3/4 ton 3.73 rear and it was a dog going up mountains out west so i upgraded to a 1 ton Diesel but kept the 3.73 rear and while it would tow my new rig at 18,000 lb and 41 ft I up dated to a 350 DRW for stability on the Roads. Just a note if you get a Ford truck order it that way you get what you need/want. I still have a 3.73 rear and I order them with a slide in camper pkg that give you a heaver load in the bed.
