Smoke Machine
I want to do some testing for leaks, drafts, and airflow in and around my travel trailer. What makes a cheap, safe, easy to use source of smoke?

If you are testing for leaks in your roof, I think you just need to pressurize the inside with a fan and spray the roof seams with soapy water. Is that what you are working on? Generally, I think you just have to close all the windows and doors, figure out how to add a good fan to blow into your trailer (get a good seal for the fan in a window or in a door) from the outside. The pressure will send the air out any openings. The soapy water will bubble at any leaking point. I am guessing others will be able to give better details than this if this is what you are looking for.
