I'm happy to report that blowing air into the trailer was a success. I fabricated piece of thick cardboard the size of the baggage door and cut out an 8" hole for the concrete form. Luckily I had an 8" form in my garage so no trip to Lowe's was necessary.
Duct tape was used to seal up the door/cardboard and the form to the fan. This combination produced a lot of air in the camper. The entry door was being held open 2" by air.
I'm happy to report no leaks other than areas I knew would like the range hood vent, outside shower, and electric cord hatch.
Version 2 I'm hoping to use some plywood and build in a manometer.
Thanks everyone.
Todd
