Yes. I caulked all seams. Used marine sealant 5200 which also bonds the pan and walls together. There is enough air circulation to dry any minor moisture under the pan or behind the wall. I check via the pan inspection plate. If there is anything, I can take the door trim off and check from there as well as get air circulating using a shop vac.
