Thanks for your input. I discussed your comments with the sales manager and a friend who towed 2 snowmobiles on a car carrier with a 2014 Jeep Grand Cherokee. They are both saying that the 2014s are much improved over earlier models.
I have placed an order for the factory to build the Grand Cherokee. Every one on their lot was loaded down with extras that were nice, but not the extras that I wanted.
So now I am looking at 6000/600 E2 WDH by Fastway.
