I have Trailair hitch pin and Rideright air bag suspension. between the two of them it's as good as it is going to be. The air suspension will level the TV and the air hitch will smooth out the ride. There are several good air hitches on the market, Trailair and Moreride seem to be the most popular.
I wouldn't think of pulling without an air hitch after owning one. A little costly but one of the best purchases I have made. It eliminates wear and tear on the tv, the fiver and most of all the occupants of the tv.

We have the Air Safe 25K air hitch also. Was pricey,but well worth it when hauling. When we're home, hubby rigged up a chain lift and we remove it from the truck and sit it on a roll dolly so it is out of the way. When ready to go he hooks it back up, lifts it and I back the truck under the hitch. Hook it up and we're ready to go.
