Get on the Uhaul camper Facebook page and make a WTB post for a wheel. You might git "Lucky". That's where I purchased my last vintage wheel with the 3 little nubs for my VT16 Uhaul. Bought it for $40 plus shipping.
That must be the wheel that I sold
you. All my parts have been sold
except for two original door latch strikers and one NOS window
