Airstreams got wider and taller in several iterations between the 50s and the 90s, plus got a lot more features, bigger tanks and somewhat different structure.
There are 9 people in my WBCCI unit towing various Airstreams with F150s. I have my vintage 24' Argosy, and others range from a shinyTiny '48 WeeWind to an '03 Classic 30'er. My pickup is an '07 with a 5.4, most of the rest are running newish trucks with the 3.5L Ecoboost. There are also a couple of Tundras and RAM 1500s. These are people who travel a fair amount, all across Texas and into The West.
You can expect to receive other opinions, but I'm satisfied with my half-ton experience and am likely to eventually replace it with another half-ton.
