I assisted a friend with his 2003 Winnebago Journey DL and his passenger side storage door he had open when he chose to leave his storage garage. What I assisted him with was..... (wish I had pictures) remove the front body trim piece and the second compartment door. We ordered a replacement door from ( Colaw RV Used RV Parts | We Have Your Part
) and then pulled the color codes from his owners manual. We took all three (3) parts to local car body shop so they could order paint and then line up all three sections and paint to match the custom Winnebago paint scheme. As all the body shop had to do was carry the panels into their paint booth, their total cost to prep the repair panel, paint, seal coat and replace hardware was $275. The compartment door freight shipped from Colaw in Missouri to Ohio was $450. This saved money as he didn't file a insurance claim. Best of luck with your repairs.
