So after 3,500 miles of roaming about with Mr. Towed, my DIY Benroy-ish 5x8 teardrop, I am in the process of making some changes, some major (retrofitting a Dexter axle) and some minor. In the minor category I am considering installing a couple of mushroom vents to improve ventilation. Something like these: http://www.rvstuff.com/ez-catalog/X325604/17/17480AW
I have a Fantastic Fan/vent and with that cracked open and my door windows open a bit I can keep condensation to a minimum in most any conditions (the walls and ceiling are well insulated). However, the problem is that the air entering the windows blows pretty much in our faces. Not the best in chilly damp weather! So I'm thinking that some way to keep the windows closed but still let in some ventilating air would be nice. On the other hand, I'm a little leery of cutting big holes in my walls...
Has anyone had any experience with these? Or other approaches to adding ventilation?
Thanks!
Steve
