We've had our Haier 10.1 installed for a full year now, with zero clearance on the sides, and the top and bottom gaps sealed on the inside of the coach, and zero problems. The back has the normal ventilation from the original Norcold installation, but I do close off all but half of a slot at the bottom in colder weather. The fridge only draws a maximum of 2 amps when running, and except in very hot weather, has a duty cycle of about 30%. Overall we're very pleased with the fridge, especially the additional room inside and stable temperatures. The sub-zero freezer temp is nice as well, easily keeping ice cream hard.
