We bought ours from: (company unknown) 2101 Industrial Parkway, Elkhart, IN 46516 Phone: 574-295-0234
Sorry, we don't remember company name but purchased 4 (2 with Beaver on them) and 2 plain about 6 years ago. I change them when they start looking like they have been scratched because those are small cracks and I don't want one shattering when someone is using it to enter the coach.
