Hey Dandy - I had a Tracer 3150 with the outside kitchen, and now a Crusader 335BHS (also w/ the outside kitchen), they both have the same kind of issue you're talking about
: some water will get into the lower channel under the door and into the latch for the door. I never had water get into the camper though - the seal always stopped the water, but the latch did end up corroded from water on our Tracer. There's a recent thread about the outside kitchen doors here - link
- might want to read through that....
Good luck, and Cheers!
