How much pressure

Markdoane,

That is what I'm trying to prevent. Many times you hear about the person with the rotted floor that had no idea they even have a leak.

In the end, I may just use all three Fantasic Vent sucking air into the trailer to do the test. I know if I have them all blowing out at the same time it will suck the door shut.

I think that .5 psi is to much and you will create leaks. Thats alot of volume. Airstream construction methods will not support pressurization.
