Hi, Timmy, I had a similar issue, with my '03 Bambi. I beefed up the weatherstrip on the door, with the addition of some of that stick on weather strip, such as you find at Home Depot. The real cure, I believe, is the other step I took. There is a company which makes a stick on plastic gutter rail. I found mine at Camping World. It comes in black and looks as if it belongs there. The railing can be warmed up in the sun, so it becomes pliable. Follow the directions. It has a sticky back for ease of application. Start at the lower right side of the door, bend the stuff over the top of the door, then down the other side. Voila, no leak. I think you'll be very happy.
