Airstream Interstate 24GLX
2027 · Sprinter 3500 Extended luxury tourer · seats seven, sleeps two
The Airstream Interstate 24GLX is the luxury tourer of the factory Class B pool: a 24-foot-9-inch coach on the Mercedes-Benz Sprinter 3500 Extended chassis (170-inch wheelbase) with all-wheel drive, air ride suspension and the segment's benchmark fit and finish. Its party trick is seating: belted places for up to seven, the most in this pool, wrapped around a lounge interior with Ultraleather seating, power day/night shades and two smart TVs, while the sleeping count stays at two on the 70-by-82-inch bed the power rear sofa folds into. Airstream publishes no base MSRP for the 24GLX; an optioned 2027 unit at Airstream of Minnesota stickers at $312,600, and that dealer figure is what this site displays, labeled as such. Fresh water is 23 gallons, per Airstream's own specification page. It is built for couples who tour long distances in first class and bring people along for the day.
Who is the Interstate 24GLX for?
The 24GLX is built for luxury travelers who use the van as a vehicle, not just a bedroom: couples who tour long distances, host family on travel days and tailgate in comfort. Nothing else in the pool belts seven people, and the cabin backs the claim up, with swivel cab seats, a modular pedestal table, marine woven flooring and Airstream's signature aluminum ceiling and trim. The running gear is the touring spec: Sprinter 3500 Extended with all-wheel drive, a 2.0L high-output turbo diesel (208 hp, 332 lb-ft), air ride suspension, all-terrain tires and a 5,000-pound tow rating. Off-grid equipment is standard and serious: a 10.3 kWh heated lithium bank (17.2 kWh optional), 400W of solar, a 3,000W inverter, heated fresh and gray tanks and diesel hydronic heat and hot water, under a 2-year Airstream limited warranty. If the travel itself is the luxury, this is the benchmark.
The compromises are price, length and sleeping count. There is no manufacturer base price to anchor on: the $312,600 figure is one dealer's sticker on an optioned unit, so every transaction is a negotiation that starts from whatever sticker the unit in front of you carries. At 24 feet 9 inches on the extended chassis it is the longest van in this pool, with the parking and maneuvering manners to match, and its 1,267-pound net carrying capacity is modest once seven seats are filled. And it sleeps two, period: seven belted seats make it a group day vehicle that hosts a couple overnight, not a family camper. Buyers who need berths should look at the Winnebago Solis; buyers who want this finish with a published price and a smaller footprint should look at the Grech Terreno.

Specs verified October 16, 2026 against Airstream's published data.
Airstream publishes no base MSRP for the Interstate 24GLX: neither its product page nor its specification page carries a price, so the figure shown is a dealer's sticker, labeled as such wherever it appears. The $312,600 is the MSRP on an optioned 2027 unit at Airstream of Minnesota (stock 116403), recorded October 14, 2026 and re-corroborated in the same live listing on October 16, 2026. Airstream does publish a starting price for the sibling Interstate 24GL, from $274,900, recorded here and in the notes as lineup context only; no 24GLX base figure exists to display.
Airstream rates sleeping capacity at up to two, on the 70in x 82in bed formed by the power rear sofa and ottoman. Belted seating capacity is up to seven, the highest in this pool.
Airstream's spec page lists a space-saving wet bath, a foot-flush toilet and a macerator pump system with electric retract for holding-tank disposal. An earlier ledger entry described the bath as 'fully plumbed wet bath with macerator system, heated' from an Airstream lifestyle article; the specification page is now the source of record.
Upgraded from dealer-only to manufacturer-verified on October 16, 2026: Airstream's specification page publishes 23 gal, the same figure previously recorded from a dealer listing; the dealer listing still agrees.
Listed as 'Waste Tank' on Airstream's specification page; discharged through the standard macerator pump system with electric retract.
11,030 lbs GVWR on the Sprinter 3500 Extended; unit base weight 9,763 lbs, net carrying capacity 1,267 lbs, tow capacity up to 5,000 lbs, per Airstream's specification page.
Heated fresh and gray tanks and diesel-fired hydronic heat and hot water are confirmed on Airstream's specification page; the Timberline name for the hydronic system is per Airstream's support documentation (support.airstream.com winterization article).
What does the Interstate 24GLX actually cost?
Airstream publishes no base MSRP for the Interstate 24GLX, so there is no manufacturer price to display, and we will not dress a dealer's number up as one. The figure this site displays, $312,600, is the MSRP sticker on an optioned 2027 unit at Airstream of Minnesota, recorded in our fact ledger on October 14, 2026 and re-corroborated in the same live listing on October 16, 2026; it is labeled a dealer listing wherever it appears on this page. For lineup context, Airstream does publish a starting price for the sibling Interstate 24GL, from $274,900, which is the closest thing to a factory anchor the 24-foot Interstate family has. Against the luxury Sprinter pool, the 24GLX's dealer sticker sits above the Grech Terreno at $290,400, which is Grech's published MSRP, and above the Coachmen Galleria at $236,822, also a dealer sticker, since Coachmen publishes no price either. What the 24GLX premium buys is the Airstream cabin, the seven-seat layout and the brand's dealer and service network, the deepest of the three. Our chassis comparison covers how the Sprinter stacks up against the Transit and the ProMaster.

Frequently Asked Questions
How much does the Airstream Interstate 24GLX cost?
Airstream publishes no base MSRP for the 24GLX, so there is no manufacturer price. The figure this site displays, $312,600, is the MSRP sticker on an optioned 2027 unit at Airstream of Minnesota, recorded on October 14, 2026 and re-corroborated in the same live listing on October 16, 2026, and it is labeled a dealer listing wherever it appears. Airstream does publish a starting price for the sibling Interstate 24GL, from $274,900. At $312,600 the 24GLX carries the highest figure in this pool, above the Grech Terreno's published $290,400 MSRP, with the caveat that one number is a dealer's sticker on an optioned unit and the other is a manufacturer's starting price.
How much fresh water does the Airstream Interstate 24GLX hold?
23 gallons, per Airstream's own specification page, re-verified on October 16, 2026; the tank is 12V heated, as is the 24-gallon gray tank, and the waste tank is 11 gallons. That puts the 24GLX mid-pack among the luxury Sprinters: below the Grech Terreno's 26 gallons and the Coachmen Galleria's 26, above the Winnebago Revel's 21, and well below the Storyteller MODE's 37. The figure was previously recorded from a dealer listing only; Airstream's spec page publishes the same 23 gallons, so it is now manufacturer-verified.
How many people can sleep and sit in an Airstream Interstate 24GLX?
It sleeps two and seats up to seven, both per Airstream's specification page. The seven belted positions are the most in this pool, and the two berths are the 70-by-82-inch bed formed by the power rear sofa and ottoman. That split is the 24GLX's identity: a group touring vehicle for the day that hosts a couple at night. The Grech Terreno seats up to five and the Coachmen Galleria up to four, and both also sleep two; buyers who need four berths included should look at the Winnebago Solis, which sleeps four in both floor plans.
What kind of bathroom and toilet does the Airstream Interstate 24GLX have?
A space-saving wet bath with a shower and a foot-flush toilet running to an 11-gallon waste tank, per Airstream's specification page; the tank empties through a macerator pump system with an electric retract, and there is no cassette toilet. That matches the luxury Sprinter pattern in this pool: the Grech Terreno and Coachmen Galleria also run flush toilets to black tanks, while the Winnebago Solis is cassette throughout and the Thor Sequence and Tellaro fit a cassette on their 20U floor plans only. The macerator means the 24GLX empties at a dump station like a conventional motorhome, with the pump assisting the discharge.
How does the Airstream Interstate 24GLX compare with the Grech Terreno and the Coachmen Galleria?
The three are the pool's luxury Sprinter tier, and they split on size, seating and price transparency. The 24GLX ($312,600, a dealer sticker on an optioned unit, since Airstream publishes no base MSRP) is the largest at 24 feet 9 inches on the extended chassis, the only one that seats seven, and the only one with all-wheel drive and air suspension standard at this size, with the strongest dealer network of the three. The Terreno ($290,400, Grech's published MSRP) is the shortest at 22 feet on the non-extended chassis, seats up to five, carries the largest standard battery of the three at 16.8 kWh against the 24GLX's 10.3, and backs the conversion for 3 years against Airstream's 2. The Galleria ($236,822, a dealer sticker) is the insulation-first entry at 24 feet 3 inches, rear-wheel drive standard, with an AGM bank as standard where both rivals are lithium. All three sleep two and run a flush toilet to a black tank; the 24GLX's argument is the cabin, the seating and the badge.
