Actually, 2-2.5 inches of lift can do alot for one's off road performance. What it does is make a significant difference in one's angles of attack, departure and breakover angle. For hunting, this has meant alot more to me, and many I've known, than adding much larger tires.
When they built the current Ram Power Wagons, they raised the standard Ram 2500 about 2.5 inches. That made a real difference in it's off road performance. They only increased the tire size by one size from 265's to 285's. E
