U-Haul car trailer experience?
One thing to remember, and I know this doesn't apply to the original poster, but a big overhang is going to adversely affect towing. When I towed my Dodge Maxi van the wheels were placed the same as this Newport, no room to spare, and the back end of the van hanging out there was like the tail wagging the dog. Couldn't go over 50 without severe sway. I was towing with a 2500HD Silverado with excellent brakes, but thank the Good Lord for that surge brake.
