Similar expierance 1st year with our new 77 Montana HC 353RL. The rear Dometic Blizzard leaked from return Air duct. Dealer seemed unaware if issue so I gave them a copy of service bulletin from Heartland describing the same leak on poor design top cover issue and holes needing sealed in housing base of Blizzard unit.
Several visits to dealership and them doing water leak test. The final fix was replacing A/C unit (Keystone approved) with Same type but supposedly updated design. NO LEAKS since Sept. 2017 but keeping my eye on it. Dealer cautioned me the seal may need regular service as they felt arch of roof and the A/C base mismatch may be a factor of poor sealing in future.
