I created a simple and inexpensive leak test method with a blower fan and foam board. Cut a piece of 1" foam board to fit a side hatch. Cut a hole in the board to match the outside of the blower fan. Create a duct with duct wrap and secure to the foam board with duct tape. Insert the board into the hatch and seal the edges around the hatch with duct tape. Set the blower fan on a table and connect to the silver duct.
My blower fan is 3/4 hp with up to 3500 CFM airflow, more than enough airflow.
Open all of the doors on the cabinets, closet & bath. On the outside, spray the joints, door, hatches and any roof openings with soapy water to detect any possible leaks. If you detect a leak, you can repair the leak and re-test.
Do not open the walk-in door while the fan is running as it could knock you in the face due to the pressure.
See the attached pictures.

Re: Inexpensive Leak Test
Thanks for very good info. I see Home depot sells a fan similar to the one in your picture. I would like to do such pressure test on my BF. And had doubts whether a home made system would work? Thanks

Re: Inexpensive Leak Test
Why not just use your existing Fantastic fan for this purpose. Set it to blow air inside on its fastest speed setting and close all doors and windows. Should work just as well.

Re: Inexpensive Leak Test
I do not think the Fantastic Fan would provide enough CFM to pressurize the cabin to do a leak test with soapy water.
