To comment on Richard's comment, I've towed various vehicles behind my Newells and Foretravel and never felt any "wiggling" from the toad. But we recently towed my Lexus GX470 from Louisiana to Amarillo with my Roadtrek. The RT weighs about twice as much as the Lexus. It was a hand full towing, I felt every defect in the road. There was a small amount of play where the towbar slips into the receiver. With the short wheelbase on the RT the Lexus was the tail wagging the dog. It was controllable but required careful attention. When we got to Amarillo a strong gust blew me into the next lane! Enough! I pulled over, unhooked, and Cindy drove the Lexus from there to Colorado. The rest of the trip I was driving into a 30+mph headwind. All this to say that the Newell is large and heavy enough that you won't feel what your toad is doing while you're driving. If you do have an extension make sure there is NO play. And if you add a lift and larger tires and find that the Jeep drives differently on the highway you can bet it'll still be doing that when towed.
My days of towing a vehicle are over.
