prop66 - good suggestion on the level. trying now to see if it will help.
Interestingly didn't happen in heavy rain in same spot a week ago.
That is directly from having the fridge side of the trailer higher than the off-fridge side. I had noticed this effect on many RVs, not just Airstreams. The easiest fix is to make sure that side is the "low side", although you can still get wind-driven rain in the opening.
