I did that with about a 1000 lbs of marble chips. I was a little shocked when I noticed that I could see over the hard top. It handled it well enough, but the steering and brakes were a bit squishy. Next time, I'm getting a trailer. (No lift, stock 33's)I wish I had taken a picture but I was in a hurry due to incoming rain.
I hauled 15 80# bags of Quickcrete in the cargo area of my JLUR. Needless to say it was squatting a little. It handled the load a lot better than I thought it would being lifted on 37's.
