As I found out when I went to Camping World I was told there are four different kinds of plastic vent covers. WOW who would have guessed ? I decided just to replace the old vent with the bigger Maxx Air vent. As I already have the underfloor whole house attic vent monster fan. I am deciding on installing some smaller computer vent fans into the ceiling they only run at about 30 - 40 db , they also come with speed adjustments and cool blue lights :-)). Stay tuned to see what happens ?
The old vent was only 4 years old , parked in the driveway. It might only last 2-3 years on the road. Out with the JUNK - in with the new and better stuff
