Water leak in return air vent

2021 4001lk. Anyone else experience this issue???
Water leaking from bedroom return air vent after rain. Mobile tech removed AC shroud and we both witnessed that the AC unit was offset from the hole cut in roof. Actually two of my three AC units were installed in this manner. Of course Funtown (or as I refer to Bumtown) said that would need unit for 3 to 4 weeks. So I am paying rv tech to make repairs..

I had a similar problem with my unit when I first got it. I discovered that the lag screws that they use to hold the AC units on the roof are the problem. The screws are driven through the roof and into the top of the ductwork. I bought a few tubes of self leveling roof sealant and sealed the around the four AC roof fasteners and the leak was solved. Squirt the caulking under the upper side of each bracket to cause the water to go around the bracket and not under it. The more stuff you do yourself the better you will understand your unit and you will save money and keep your unit out of the repair shop.
