I don't know about the newer ones, but I have had several Grand Cherokees from the 1990's to 2002 models. Currently on my second 2002 after the first one had almost 300,000 miles on it. The last ones have been the Overland model and I have put another 2" lift on them. With slightly oversized tires, tuned suspension and heavy duty sway bars with quick disconnects, they offer an amazing ride in the rough stuff. I have had mine on trail rides where heavily modified Wrangler guys were simply amazed at what the slightly modified Grand Cherokee Overland could do with great comfort. Mine are not wildly modified since they are daily drivers averaging about 35,000 highway miles each year for work and still ready to play too. I have also had older Toyota's and they are great but not as comfortable. Nice to have the 8 cylinders too when you need them. I think they suit your intended purpose about perfectly if you would slightly modify the suspension as discussed.
