If you haven't used the tow bar yet, and before you get too invested in the setup, you might want to read the following thread:

Call Blue Ox, and ask them specifically how long they support their tow bars. You stated that yours is a 2012 model . . . Ask BO specifically if they still support that specific tow bar . . . lots of people report that BO won't support their tow bars beyond 5 years of age.
Also suggest you google "tow bar failures" and compare brand failures, and people's experience with which companies stand behind their products, and which don't . . . .
Consider:
Demco: Limited Lifetime warranty, Original owner only. However, Demco stood behind their product, and repaired our 12 year old tow bar even though we were the 2nd owner. No charge.
Blue Ox: Limited Lifetime warranty, but if you read the actual warranty, it really doesn't cover much of anything.
Roadmaster: Made in America, Lots of good reviews, Limited Lifetime. We purchased a Roadmaster this year because we purchased a heavier toad, and the Demco wasn't rated for it.
Good luck in whatever you decide!
