The Blue Funk has a carrier mounted on the right side. Of course, it was an add-on. I've not seen another like it. It rides rather high compared to the others I've seen. I added a bed rail and it caused me to have some more aesthetic pleasure.
Olblu49 made an interesting point: He thought the spare on the passenger side might equal out the weight distribution. I don't know, but it looks cool. And it's as the old saying goes: It doesn't matter if we win or loose. It's how we look playing the game.
Good luck in your endeavors, AbleMabel.
