RV Repair: Interior wall / ceiling paneling, rv dealer, interior wall

Question
I'm looking for a source of wall / ceiling paneling to replace a damaged section in our Class C.  Do you have any suggestions?
Thank you!

Answer
About the only way you are going to match it is to go through the manufacturer of your unit to get some.
If you don't care if it matches, then you can go to any large RV dealer and they should have some in their service dept.
Or you can go to Lowes or Home Depot.
