I called a local Travel Trailer shop near me that has been in business since the 50's and they said they have never heard of doing a pressure test to check for leaks. Who does this type of thing and what does it cost?
You can DIY with a furnace blower, a leaf blower, or any fan/blower that moves a good bit of air. The idea is to introduce air into the interior until a positive pressure differential is achieved. 1/2"-> 1.5" of Water column is an accepted range. When the pressure has been achieved, the exterior is sprayed with a water-soap solution. Anywhere there is a passage to the interior will have bubbles forming on it.

If I knew this Forum would sticky the process as I do it, I'd do a write up and description of the testing. Unfortunately, everytime this comes up and I post up the info and pictures, it fades into the archives. The information is buried in my restoration thread in my signature line, "the Cowboy/Hilton".
