Lock Cylinder Gaskets

[vwgtiturbo]

Hello all, from a new camper! I'm just getting started and finding a lot of info that is going to make this whole thing loads of fun!

We just bought a 23DBH Grey Wolf (manufactured in April) and it looks like it was put together with dry rotted lock cylinder gaskets on the storage cubbies. Is there a standard for these things, such that I can simply hop online and order them to replace? I'd hate to go through the hassle of trailering up and towing it to the dealer for warranty replacement for something so simple and cheap to replace.

Thanks in advance for any advice! I look forward to learning a lot, and one day sharing a lot as well ;-).
