We had our TT into the dealer last Nov. for some warranty items and I got them to check all the exterior caulking and they found some areas around the front cap that needed some caulking. Exterior caulking seems like something that shouldn't be overlooked even on a newer unit.
A hydraulic engineer would be able to formulate an answer: cubic feet of inside of RV (say 1600 cu ft. with natural pressure of 14.7 psi. How much additional air in CFM is required to raise the pressure .2 psi if the container was absolutely sealed?) From the answer you would have to allow for leakage since no RV is perfectly sealed.
