98 Fleetwood side trim

I've been lurking here a long time but I guess this was a perfect time to to join. Anyway I have a 1998 Fleetwood Prowler. These RV's have the rubber side trims instead of those aluminum ones with the insert. These are just glued on I think. These usually come off with time. Where can I fine these side trims?, I've looked all over. These are made of rubber I think and about an inch wide. Thanks in advance.
