Installed this vent in a casita, with a simple spacer to move up and away
from my balding head. When moving the trailer through rough
tree covered roads, the top can be lowered to almost flush with the roof.
Used 1 1/2" of resin coated plywood, all hardware was SS and aircraft locking
nuts were used.

Looks great! Who made the vent cover?

Jack;

It's a MaxxFan, by MaxxAir all-in-one unit.

I installed one in our Scamp. Since were are not as tall, I made a spacer to fit inside dropping the screen and controls down about an inch from the ceiling.
