Additional cons that PainRoller didn't mention:
1) Decreased rear visibility (although Celt did mention that one)
2) Rig becoming longer overall - this can be an issue if you park in tight/short parking spaces or in a garage often
3) The "pain in the ass factor" with having to open the swing arm every time you need to get into your cargo area
In a nutshell, I can sum it up like this: you're trading everyday/street ability for overland/off-road ability. You need to decide which is more important to you, based on how you use your rig. Then you can narrow down the features/options/designs that are most important to you and choose the right bumper for your needs and budget.
Most of the time, I regret getting mine. I have "no ragrets" on my choice of brand or the build quality, despite some horror stories I've heard about previous versions of the Hefty rear swing arm bumpers. My arm and latch don't rattle at all, my tire sits at a nice height, and the bumper is solid and perfectly functional. For me, # 2 and # 3 above are the two biggest issues. Every time I'm flinging that swing arm open to grab a camera or other equipment at the scene of an incident I'm trying to shoot, or every time I can't open my hatch in a parking lot of a grocery store or in my garage because the arm can't open wide enough, or every time I get dirt and grime on my shirt from brushing up against the tire while trying to squeeze between the back of my rig and the back wall in my garage (or even worse, when it happens to my wife and she gets mad at me for it!), I regret it. But then when I'm off-roading, I love it! I love the easier access to the spare (although, thankfully I haven't had to use it), the mounting point for my trasharoo, and the overall "more serious off-roading" look it gives my rig.
Despite the fact that my rig is no longer my commuting/every-day vehicle, it's still my "work truck" when I'm shooting news stories, and I think that's when I dislike the bumper the most. The reasons I stated may not be an issue for you. And some can be overcome with a different design or features - like double arms to open easier in parking lots or tight spaces (although that also means you now need to have space on BOTH sides instead of just one, so there's even a trade-off there). I've seriously been contemplating finding a new loving home for mine and replacing it with a non tire-carrier bumper and putting my spare back underneath, so I can still have the recovery points, strength and integrated hitch of an aftermarket rear bumper without the hassle of moving a tire out of my way all the time. It may sound dumb, the trasharoo mounting to the tire is the one thing that's kept me from removing the bumper at this point.
If someone could design a bumper with an EASILY removable swing arm that would allow you to move the tire back under the rig for "everyday" use, they'd get my business in a second. As with all other reviews, YMMV.
