I did not find a lot of information on the site specifically about Salem vents, so I thought I would ask...
When I place my trailer order; I plan to possibly substitute a front window with a Salem vent (metal construction with open and close capabilities) for a vent path of fresh air. I was only originally considering the front window for its ability to crack open when I need cross flow circulation to my rear window located in the rear trailer bathroom area; or if the trailer ends up being "sealed" to tight after my insulation work. (There will be no roof vents). One drawback i can see- there is no screen for bugs. Is this a big deal, do bugs (flying or crawling) make their way through these while open- especially if I were to leave open during storage? <or a mouse..?>
Also:
Does water come in through the vent while open or closed? When driving down highway, or just sitting while camping?
Would it be advised to mount in a horizontal fashion as opposed to the standard vertical mount in an effort fo reduce chance of water intrusion? - I will not be using this in the standard sense with one mounted high and one low on opposed walls- for air while going down road....
Thank you in advance for any input!
