I've owned two TTs and now own a fifth wheel. The fifth wheel is much easier to hook up to and go, is easier to back in, and feels more stable on the road. However, if you decide to go with a TT, as long as you get a weight distributing hitch and a good sway bar and drive sensibly, you'll be fine. There are advantages and disadvantages to both.
