Hey "battery man",
Welcome to iRV2, we’re really glad to have you here as a new member and are looking forward to reading your posts about your RVing experiences and adventures. You’ll find a great bunch of folks on this site who are
very knowledgeable of RVing, the rigs we use, and the places we go in them.
Check with
Singleton's RV & Salvage, he has an old website up that says he has any size Fayette wheel, website is 3 years old though.
I'll also put a link to your post in the Vintage Forum, maybe someone hanging out there will be able to help you find one.
Again, welcome to iRV2, we’re glad you joined.
