Domestic blizzard leaking water

Have done all the mods/ been to more than one rv dealership, still getting water in return air ducts, wife’s getting tired of water buckets when it rains.

Take the cover off the unit and see if there are open holes in the base. Dometic made extra mounting holes and sometimes they are not plugged and other times the caulk they used cracked and came out making a drain hole into the duct work.

Sorry, It's from the Heartland owners group and the bulletin explains how to repair the water problem entering into the duct work on Blizzard AC units. It explains how and what holes to plug up and where to drill new drain holes.
