I'm CindyL's husband and yes, we do have UHaul
hubcaps. However, another UHaul Camper has already inquired about them and has the right of first refusal. The kicker on this, however, is that I have to find them with all the other camping gear in our garage! As my wife has said, that might be a 2 year search!
If you have the original UHaul wheels with the small nubs for hubcaps, then they would fit a CT or VT. The new wheels from UHaul do not have the little nubs, so they don't work on those without drilling holes for another type of attachment.
