If you can't do an accurate and complete pressure based leak test, hire a registered Sealtech operator to do the test. It will be the best $100-$150 you will spend for maintenance.
It is not that hard to DIY pressure test. You do need a volume of air to raise and maintain the entire pressure of the cabin to 1" of pressure. I used a furnace blower and a DIY manometer. The pictures are in the Cowboy/Hilton thread in my signature, page 30. I plotted the leaks on individual pieces of paper, one for each surface. Even after carefully sealing all joints in the TT, I discovered 2 dozen small pinhole leaks.
