-The industry standard for RV roof vents is 14"x14".((http://www.arizonarvpartscenter.com/standard-14-x-14-rv-vent-lids-s/468.htm))  OEM vents are often substandard, lacking cowling around the fan that would move more CFM.  +The industry standard for RV roof vents is 14"x14"((http://www.arizonarvpartscenter.com/standard-14-x-14-rv-vent-lids-s/468.htm)) and can be as simple/inexpensive or fancy/expensive as one wants.

 +===== nonstandard vents =====
 +
 +Although 14x14" vents are standard in the camper world, there are other (usually smaller) options. The smaller vents often have greatly-reduced flow, as measured in CFM((cubic feet/minute)). Some of the smaller ones give cubic feet measurements, //but are given for an hour//.  Example:  900 cubic ft/hour == only **15** CFM.

 +
 +'Dwellers looking to maximize solar real estate may be able to mount low-rise vents //under// raised solar panels.  
 +
 +
 +==== mushroom vents ====
 +
 +RV-style mushroom vents are typically mounted in 5" to 6.25" holes.  They may be always-open or openable, [[https://amzn.to/2UPaOF0|powered]] or passive.  [[https://amzn.to/2UL5ulK|Solar powered versions]] exist.

 +==== wind-powered vents ====

 +[[https://amzn.to/39K80wV|{{ https://m.media-amazon.com/images/I/61kgY7E413L._AC_UY218_ML3_.jpg?125}}]][[https://amzn.to/39K80wV|Flettner-style vents]] use breezes (5-10mph+((https://www.flettner.co.uk/flettner-frequently-asked-questions/))) to power the vent.  Otherwise it acts as a passive vent.
