Just my $.02 I've done a lot of wheellin in my time and a lot of times it boils down to the driver and of course the word "off roading" and wheeling" is terms used loosely. An experienced driver can take an H2 and do a lot just as he could a Titan or a Jeep all in stock form.Lot of times those words are used once you leave the blacktop and drive on gravel, it's amazing what some people call off roading I could drive a volkswagen bug on their off road trails and make it through. Most vehicles despite being 4 wheel drive if not specifically modified for real off road and is stock is limited to what it can do if you want to drive out unscathed, meaning if you attempt to do serious off roading in any stock vehicle be prepared for damage and wear. Again depends on where you go, your vehicle's capabilitites and how much guts you got, and if really a true off road trail but go for it and enjoy and put the Titan to the test with in your abilities. If you have never gone off roading before go for it you have to start sometime and put the 4 wheel drive to use. I bet once you do you'll love it so much you'll be going more often. As far as going with the H2 club go for it man I think you will have a lot of fun that's the main thing, not if your Titan or there Hummer off roads better.
