Thai, you know I appreciate the information you bring to the table and I don't want to sound like I'm bashing or anything b/c I'm not; but the tire comment makes no sense. Upsizing tires is the cheapest and most effective way to increase ground clearance. A vehicle that is taken offroad into anything moderate or above should have the tallest tire it can fit at full compression in my opinion. IF 31" is the tallest the G can fit then that makes sense. There is only one thing that will get the diff off the ground and away from rocks; that's the tire! I am sure your G's drivetrain should be able to handle upsizing to at least 33's (285/75's for us 16"ers) even if it was for trail use only (ie 2nd set). Hell it would be no more stress than the drivetrain sees with AMG's G55 setup!!!
