i have a 2006 grand cherokee Laredo edition. I've been looking at various website for towing hitches. I've found them that are custom fit for my model and everything, but when i look at the underside of the jeep, my spare tire is about 2 inches from my rear bumper, and my chassis comes up at like a 40degree angle from the rear to the rear bumper. Is a towing package really gonna fit correctly on my jeep???
