Sharp Hooks Matter
If you're towing down the street skip the spare hub. Towing any distance it can be difference of an under 1 hour delay or good luck being broken down on the side of the road who knows where and for how long wishing you had forked over the less than $100 for a spare hub. I just have a mental picture of being broke down on Alligator Alley between Everglades City and Homestead - not good. If you leave your boat & trailer on the side of the road to shag another hub, what do you think you will have left when you get back? In a word - insurance.Why the spare hub? Do they tend to overheat and fail?
