MY DP is 40ft and my enclosed, 1ft extra high, trailer is 32ft. Don't know the tongue weight but I imagine the trailer loaded is over 10,000lbs and has 3 axels. Also I use no weight distribution bars, just hook it up. I have towed this all over the East for close to 18, guessed at the 20 above, years and have never had a problem. When the car is in the trailer the front wheel is centered over the center axel on the trailer and the Scooter, generator, tools etc are in front of it. lots of room in front of the car. Went to Gainsville FL the day after Christmas, 1000mi round trip uneventful.
