Very Low on Driver Side

Howdy,

I have a 2011 Rhino, all stock. I use it as a utility vehicle on my mining claims. I always drive with 2 people. We are both about 250lbs.

If you are standing at the front of the Rhino, the drivers side is always lower. It's enough that when I am, driving it always seems low, enough to make me stop and look at it. Almost like my tires are flat, but they aren't.

Any ideas, suggestions or places to start looking? I figured I would ask for some ideas before I haul it up to the dealership. Thanks!
