Snow is worse than rain

[EMD360]

We took the cover off for a March trip that we had to cancel due to the heavy snow and wind during spring break here. Because I had de-winterized, I left the heat on and ran an electric oil heater inside.
Heat inside and snow outside seems to suck in water. Yesterday when I turned off the heat I noticed water infiltration in the cabover above the left window! The material at the ceiling is darkened.
Of course that is a sickening feeling in the gut. I noticed moisture before we bought the cover in the front cabover corners after such a snow with heat turned on inside. I recaulked and there were no leaks all summer despite heavy rainfall.
It may just be time to recaulk again, but I'm thinking a full eternabond taping for the front seams is in the future. A garage or awning might be nice but we are too busy working on our house remodel.

Take the time from your home remodel and apply the Eternabond. Your RV will thank you.

I feel for you EMD360. Hopefully it's minimal and can be addressed with just a little effort. Hopefully rav's comment about condensation is what really happened. But dry un-humidified heat in a motor home should not build up condensation.

I wish the RV industry standardized using seamless buckets for front cab-overs. Then we would never read of these stories.

it might be condensation - I would check to see if there needs to be insulation or something added to the inside to prevent the heat/cool from creating moisture.
