I realize things break for no reason, even with the best of preventive maint. If you don't have a spare tire carrier, you can get a spare tire & hub carrier to mount a spare hub & tire on, won't have all that stuff in the tow vehicle and you know where it is. Just have to put the tools in the tow vehicle/boat. Make sure you get a suitable lock to protect your investment from parking lot thefts and such. A complete hub is the best way to go as trying to remove races and shattered bearings on the side of the road would not be the least bit fun.
GO BIG ORANGE !
I meant to behave, but there were just way too many other options available at the time.
