In answer to the original question about the endless breeze fan....
I have used one for many years in a variety of small rigs. The same one..its very durable, seeing almost daily use during the summer months, and also winter months when I lived in Arizona. Note that I am a full timer and have lived off grid for a majority of the last 6 years.
I did not install a vent version for all the reasons others have posted here. The Endless Breeze is a phenomenal little unit and works, well..., Fantastic! At high speed, it only draws around 1.5a, and it hardly puts a dent in my single group 27 battery
, charged soley by 150w of solar
. It is on its own circuit, and has nothing to do with my convertor.
Storage is not an issue, it is so thin that I simply slide it into my closet, upright, and you hardly know its there. The feet rotate so in takes up no space wider than the case itself.
Admittedly, the Exhaust/Intake selection is pretty low tech. You have to turn it around to get what you want :-P Also, I have had the roof version in my 17ft Burro
, and yes, it is slightly "gooder" to have it there, but for most circumstances, the difference is negligible in this size rig. (I am currently in a 17ft Leocraft)
