There are many folks that tow larger Airstreams not using ½ ton, ¾ ton or 1 ton pickups. We saw a few at the International Rally in 2015.
The CAT scales coupled with weight distribution hitches and reinforced receivers allows many non-truck vehicles to tow.
We cut off the 1,200 pound rated factory receiver on the 2012 Dodge as there were a few failure reports of the welds and I knew the 2013 25FB International Serenity tongue weight was 1,175 pounds. We installed a CURT model 15049 rated at 2,550 pounds tongue weight and a 17,000 pound trailer. I knew that capacity would cover any Airstream trailer made.
Our 2007 Mercedes ML320 CDI had a hitch reinforcement done at CanAm on the recall repaired factory receiver. When I towed the brand new 25FB home, the Cat scales reported all weights were within limits. After loading the 25FB for camping and having my wife also in thecae, those numbers were exceeded. Thus the truck acquisition.
The 2015 23D International Serenity loaded for camping and our gear inside the Mercedes crosses the CAT scales with adequate weight margins. That is the appropriate sized Airstream for my car.
