We were shocked to find out that our 1986 Holiday Rambler had antiquated wheel rims! This travel trailer didn't come with a spare tire and we thought we would just be able to match up the rims and go buy one. HA! Easier said than done. I searched in vain on the internet and found only that this was an extremely rare, hard-to-find rim. Good luck, it seemed to say.
That is, until I contacted Tim Heintz, the famous (young) trailer restorer from Panama City, Florida. (Here's his e-mail: email@example.com.) Bless him, he wrote me back immediately and told me that Vintage Trailer Supply in NJ had brand new ones! Three different sizes! Here is a link for them in the online catalog:
