I have the Garvin Wilderness bumper for my XJ and love it. It is a VERY stout piece of equipment, and I would buy another in a heartbeat. I like the vertical positioning of the hi-lift jack, the class II hitch, and two solid recovery points. The hinge is very heavy-duty, with a grease zirk for age. It has the availability of accessories, such as the jerry can mount, axe/shovel mount, antenna mount, and above-spare rack. A lot of engineering is involved with this bumper system, and the welds are beautiful. Due to the weight of the bumper, it includes unibody reinforcement as well, so it doesn't tear any metal. It comes powder-coated, and looks slick with the 97+ XJs because they can retain the rear body molding (with a little trimming on the passenger side for the hinge).
Only a couple inconveniences with this bumper system. The license plate repositioning somewhat interferes with the threaded bolt style latch, but with some imagination, I'm sure there's an easy solution. And with all that weight on the swing-out when it's open, the body tends to lean to the passenger side a bit. Not a big issue, just looks... funny.
I give this bumper an 'A'. Quality stuff from Garvin.
