Im just gonna add my .02 I just traded a 04 Jeep Grand Cherokee Limited V8 , for my 01 X5 4.4 , the jeep had 11,000 miles on it, the X has 55,000 , every one of those 11,000 miles I dreaded, I could honestly tell you I would absolutely NEVER EVER buy another jeep and I would advise you to do the same , in fact dont buy any american made automobiles. I have two friends with large boats , one has a infinity FX45(with 20 inch wheels) and the other has a 04 4.4 X , both are very satistfied with their towing capabilities , so you have many options other than the jeep, I wish you luck with whatever choice you make
