2001 Winnebago Journey replacement parts - need help finding

If you go to winnebagoind.com and select resources, you will find drawings, manuals, and for mine at least a full parts list for my specific serial number as well as 3D walkthrough drawings of every subsystem where you click a part and the part number is on the right. Often, when I google those parts they come up on Amazon.com through the Winnebago store directly. I've got antennas, wipers, etc. that way.
