At the risk of becoming a PITA, do yourself a favor and take a serious look at the Pinzgauers. I got mine after my 2 by Polaris left me stranded on a medium incline.

The Pinzgauer 4 X 4 can carry up to 10 people or a one ton load. It will do a 100% grade, has a 45 degree angle of approach and a 45 degree angle of departure. Supposedly it will take a 45 degree sideslope, but I haven't had the guts to try that.
It has an 89 horsepower air cooled motor, portal axles like the Hummer (way before Hummer had them) all the 4 wheel drive is hydraulic which means any speed any gear. And like I said, the best part is you can drive it on the road. Top end is about 65 mph. They get from about 12 to 16 mpg of gas and everday parts (light bulbs filter etc.) are available at NAPA. These things all around are a better deal than the Kubotas, Razers, Gators, you name it.
There is a dealer in San Antonio, check out www.texaspinzgauer.com. I'll be quiet now.
