Upon Valter's recomendation, I modified the dorsal cabin vent. As the upper fuselage sits level with the ground when parked, apparently rain can trickle under the vent and drip into the baggage compartment when park. So I manufactured a small lip the prevent water from finding its way in. I'm pretty happy with how it came out, should be helpful... not that I have much of a rain risk in Midland, Texas ;-)
