We recently found a great source for parts for our teardrop. Heidi's Super Store in Oro Medonte, Ontario has a lot of stock in store and an extensive catalogue that has anything you would ever need.
We purchased rain gutters to add over the doors. They work perfect and keep rain away from the door ledge and away from the mattress. I've attached a picture.
Happy Trails everyone.

Here is the link to the catalogue.

Thanks, I think we will do the same!
