Think of it this way.
If you used 1500
pound bars, road shock will travel thru those bars, because they will not bend.
Preventing road shock, demands a bar rating that will flex.
Try this out.
Stand on the coupler when your rig is ready for the road. Jump up and down, and see how much of the tongue moves vertically. It should move a couple of inches. If not, then the rigitity is much to great.
Back then, our research showed that for a large Airstream, (tongue weight), a car should use a 1000 pound bar, a 1/2 ton truck used a 750 pound bar, and a 3/4 ton truck used a 600 pound bar, and hope for the best.
Since an Airstream MUST HAVE
a soft ride, that is kicked to the curb when excessive rated hitch bars and/or tow vehicles are employed.
Sway controls that have a brain, add a great amount of safety to towing an Airstream.
Flat fronted travel trailers, offer great wind resistance, which acts some what like a sway control. But, Airstreams do not offer that same effect because thy are dynamically pretty clean.
With the same tow vehicle, I could not tow an empty U-haul box trailer over 85 mph.
Yet, with a loaded 31 foot Airstream, I towed it 115 mph. This was all documented on film for Caravanner Insurance, what was the insurance division of Airstream.
Safe towing is not that difficult to achieve, but simple Physics must be a large part of the setup.
The cost of safe towing, is next to nothing, when you consider the cost of the trailer, the tow vehicle, and personal injury and/or loss of life.
Please make a post should you make a change.
Bigger, is not always better.
