Airstream World Traveler 22RB vs Bigfoot 25B21FB
The difference that matters
A 3,000 lb gap in GVWR is the headline. The Bigfoot 25B21FB is rated to 7,500 lb against the World Traveler 22RB's 4,500, so although it weighs 4,553 lb dry against 3,700, it can carry far more. The Airstream's cargo capacity is 800 lb, which a couple's water, food and gear can use up quickly. Hitch weights are close at 440 and 490 lb.
The equipment splits the other way in places. The World Traveler includes a ducted heat-pump air conditioner and a Truma Combi furnace and water heater, while solar and lithium are options. The Bigfoot ships with 400 W of solar, a 30,000 BTU furnace, a two-piece molded fiberglass shell with R8 insulation and heated, enclosed tanks; air conditioning is the option. Tanks also favor the Bigfoot at 34 gallons fresh and 22 black, against 19 and 12.
Shoppers who mostly camp at hookup sites in warm weather get a lighter, air-conditioned trailer in the Airstream. Cold-weather and off-grid campers will find the Bigfoot better matched to how they travel.
