I have an 04 Fleetwood Monterey. I installed a new Brisk II during winter and just took it out for the first hot weather trip. 15,000 BTU unit. I have to say I am completely unimpressed with it. First off even at night the compressor cycles off before it is really cool inside. I was going to try insulating the thermostat with something to keep the compressor on ( If anyone else has experienced this and you have a fix PLEASE let me know ) The second issue is the new style ceiling assembly. There is no ducting in it. When you open up the rear vent all the air comes out that and very little gets blown forward. If I can figure out the thermostat I guess I will have to build my own ducting inside it or buy one of the old style assemblies. If not I am going to buy another unit, either a Coleman Mach 15 or the Atwood Air Command During my trip I was only running the AC and the fridge so I was pulling about 20 amps on a 30 amp service.
