i have hauled concrete and roofing shingles on mine and it sat the back on teh ground. i mean i had the trailer really loaded and to much on the tongue because my kids were throwing shingles in it also. i probably had that 2k limit pushed and the jeep was ok stopping and starting but since it tongue loaded, the trailer kept trying to steer. i think as long as you load balanced and are careful on your stopping room, you'll be fine with the rhino on it.
i actually haul lots of stuff with my trailer and jeep but i never weighed any of it. as long as you are smart about how you load and drive, you should be fine.
I don't feel like working on anything, at this time.
