Although the local uhaul
place was less than helpful getting me a spare wheel, I was able to order one from the Norfolk uhaul
The wheel is about $25 and the tire is $50 something. I went ahead and ordered the tire as I need one anyhow.
If you are in need for the same, the man's name is Gene and his number is :
As stated elsewhere in this site, the part number is 23516006. This is the only way they have to identify this part. Asking for a "camper wheel" will not work.
