My Coleman Mach 15 (15000BTU) draws something like 18Amps
The Mach 13 only draws 9Amps... Wish I knowed that a long time ago...
I really like the underbelly idea for the master bedroom (back of bus)... I'd like to put a small 5000 to 8000 back there in the floor!!
The 5000 only draws 4.8Amps
BUT... I do the the cool down power of my Mach 15 Amperage Eater
The 24500BTU window unit only draws 14Amps...
