Keystone Passport SL 2450RK vs Airstream International 27FB
The difference that matters
On paper these weigh almost the same: 6,180 lb dry for the Passport SL 2450RK and 6,100 lb for the Airstream International 27FB, both about 28 feet and both sleeping six. The Passport's hitch is lighter at 700 lb against 875, and cargo capacities are close at 1,420 and 1,500 lb.
The differences are in layout and equipment. The Passport is a rear-kitchen plan with a 66 by 80 inch king, a fireplace, an outdoor kitchen with a griddle cooktop and mini fridge, a tankless water heater and an extended-season thermal package with a heated, enclosed underbelly. It carries more water, 54 gallons fresh and 76 gray against 39 each. The International is a front-bed plan that adds 300 W of solar, a 2.5 kWh heated lithium bank, a 2,000 W inverter and a heat-pump air conditioner, and it stands 1.6 feet lower at 9.6 feet.
Campers who cook outside and want bigger tanks fit the Passport. Those who want to run off battery and solar from the factory fit the International.
