I've mentioned these to Jason but haven't officially "hit" him up about selling them yet, but Trail Duty (
http://www.trailduty.com) has them in stock now if you want one. If you do get one, I think you will be surprised at how low of an angle (as compared to it's true capabilities) the pucker factor kicks in and knowing that you have more tilt available before it is unsafe.
For instance, both the H1 and H2 specs say a 40% side slope. That is about 23 degrees or so. But that spec from Hummer is with a maximum payload on board and a large margin of safety. I'd be curious to know the max angle some have been in the H2.
