Jeep and toy hauler

Thanks for all the infor, we're going to look at the Work and Play, we do like the Forest River products. The jeep is only six feet wide so getting in and out in toy hauler would not be a problem. It's actual size is six feet wide, just under seven feet tall and the length is 12,so l would need a 12/14 garage. I noticed that on some trailers(we're looking at fifth wheels) I would be anywhere from 300 to 500 over cargo weight, I was wondering if that would be enough to make it tail heavy or make it would tail wag while driving. Any comments on the Forest River Toy Haulers, the wife really likes the Vengeance models esp the touring model.
