Aftermarket Airstream body parts?

Hello!

I have a 2011 Airstream Interstate (white) and I'm looking for a company that sells aftermarket Airstream body parts for the Interstate.

For example the plastic chrome strip that runs all along the side of the van, the plastic around the wheel wells, and the plastic side panels. Mine have turned a little yellow and airstream wants a fortune for all of those. Was curious if you knew of any other place to order those other than Airstream?

Thanks!

You might call Airstream at Jackson Center to see if they will reveal their source.
