IMHO CW usually does not have a clue.
My 36' MS weighs at least 18K, My combined weight is 28K. I have a B&W Companion with the gooseneck hitch that leaves the bed clear. I have the TrailSaver air ride Kingpin Box. The combo is very solid and rides extremely well. My TV is a RAM 3500 Dually 4X4 the ride is very solid and stable in all weather conditions.
The air hitch is probably nice but extremely expensive and no cake walk to remove!
We have full timed all along the West coast since 11/11 and have enjoyed the ride.
