Best spare tire set up?

First… I’m the DW…and I love my rzr. It’s a 2010 and I’ve put about 4000 miles on it. So far, the only issue has been a bad CV joint and the corrected installation of the lift kit by the dealer (we’re not particularly mechanical but tried anyway)…
While I would love to have a new one… it’s just doesn’t make sense for me…
So I’m looking to add stuff to the current one.
Just read about ball joints… probably need those at some point or now for all I know. Are they difficult to install?

Also, the point of the actual question here is what would be the best spare tire set up? I’ve learned that I love to cut the sidewall for some reason (3 times to be exact) so having a spare is necessary. But having it take up room in the bed isn’t the best…

Suggestions?
