A recent post had a link to a company that performs RV leak testing by pressurizing the RV with a blower and then going over the seams with bubble soap. It occurred to me that this was a possible DIY project. The only blower I had available was a leaf blower. I cut a square of plywood to mount over the front vent and cut a round hole in the plywood to accept the blower outlet. After blocking the cab vents, P-traps and the range hood vent with masking tape, I turned the blower on and used a brush to "paint" the seams on the MH with bubble soap. It worked! I found that all of the marker lights were leaking, as well as a seam on the bottom of the cabover. Total cost was a couple of $$ for bubble soap.

That's a great idea! Nice photos!!

You can also use a leaf blower to check the automatic feature on an electric awning by blowing air on the wind sensor.

We used the method (somewhat) on airplanes to check pressurization,the best part of it is that it is simple and it works, I just never thought about using it on an RV.
