Not sure what a 'smoke' test is. Never heard of that. You mean a blower door test maybe? You pressurize the inside of the unit and use soapy water on the outside to see where the leaks are. Only method I know of.
Years ago you installed a "smoke" machine in the RV and closed up the RV. When the Smoke machine ran long enough to pressure up the RV, you looked for smoke coming out. NOT a very good way even back then. Now, the way is to pressurize the RV and then spray soapy water at ALL seams and areas and look for bubbles. Doug
