I just had the 15,000btu Atwood "Air Command" unit installed in my trailer which replaced an 11 year old Dometic "Brisk Air" 15,000btu unit. After using it last week I can tell you that it puts out considerably more air and much quieter than the old unit. I am very pleased with it. It also functions as a 15,000btu heat pump.
I am sure you will not regret your choice and purchase. Whether they last as long as the Dometic units remains to be seen. They have been used in Australia for quite a few years.
