Good w/d hitch choice for improving the ride in the TV

I agree with the post above. What you describe sounds like not enough weight on the front axle. Give it a try. Go back to the hitch that worked in the beginning and take up another link or two and see what happens.

I would not invest the money in a Hensley or ProPride hitch in your case. They are great for sway control but do not do much of anything above a normal hitch for porpoising.
