Airstream Interstate 19GT vs Winnebago Revel 44EC
2026 Class B comparison · side-by-side specs, verdict, and who each is best for.
Quick verdict
Both Class B camper vans run a Mercedes-Benz 2.0L turbo-diesel I4 with a 9-speed automatic, both sleep 2, and both share the 9,050 lb GVWR ceiling. The Airstream Interstate 19GT is RWD on a Sprinter 2500 with 240W rooftop solar, a 3,000W inverter and 10.3 kWh lithium house bank in 19.42 ft. The 18-gallon fresh water tank is the limiting boondock metric.
The Winnebago Revel 44EC variant is AWD on the Mercedes Sprinter, runs 35 gallons of fresh water (94% more than the Airstream Interstate 19GT) and 21 gallons of grey, and adds a side-facing seat plus smart multipurpose spaces and a power-lift bed over a gear garage. Both are 19-and-change feet long, but the Revel 44EC is the off-road-capable side of the Class B segment while the 19GT is touring-spec.
At $261,808 MSRP for the Revel 44EC versus $249,900 for the Airstream Interstate 19GT, the $11,908 gap roughly buys you the AWD axle and 17 extra gallons of fresh water. Pick on driveway type, not brand loyalty.

Pick the Airstream Interstate 19GT if…
The Airstream Interstate 19GT is the right Class B for couples who treat the van like a touring vehicle: paved roads, full-hookup or 30A campsites, and the occasional overnight at a brewery or trailhead. The 10.3 kWh lithium pack and 240W solar comfortably run a residential fridge and a Starlink for several days; the $249,900 MSRP nets you Airstream's fit-and-finish without paying for an AWD axle you would rarely use.
Pick the Winnebago Revel 44EC if…
Choose the Winnebago Revel 44EC if you ski, climb, ride or paddle on forest-service roads more weekends than you do not. AWD traction lets the van actually reach the parking lots the brochure photos imply, the 35-gallon fresh tank doubles your shower window before refill, and the side-facing seat in the 44EC layout makes the van a better daytime workstation than the 19GT. At $261,808, the Revel 44EC is the better truck under the Mercedes Sprinter Class B label.
