How much does a used Airstream Interstate 24GL cost?

On US RV Connection there are currently 3 priced Interstate 24GL listings, all asking between $209,995 and $253,540, with a median asking price of $216,877. Those are asking prices, not sale prices. All three are new 2026 units rather than used ones, so there is no used pricing data here to quote. Each listing has photos, so you can see the actual coach before contacting the seller.

What years of the Interstate 24GL are for sale?

Every Interstate 24GL listed right now is a 2026 model, three of them in total. There are no older model years in the current inventory, so you cannot compare year-over-year asking prices on this page. If an earlier year matters to you, the only thing US RV Connection can show today is what is actually posted: three 2026 Class B diesel coaches, all with photos.

What layouts or floorplans of the Interstate 24GL are listed?

All three listings are the standard 24GL floorplan, described as a Class B diesel motorhome on the Mercedes-Benz Sprinter 3500 chassis, with one description noting a Sprinter 3500 Extended at 24 feet 6 inches long. The layout includes a rear power sofa bed and a wet bath with a one-piece shower, toilet and sink. No alternate floorplans or slide-out versions appear in the current listings.

What should I check before buying a used Interstate 24GL?

Everything listed here is a 2026 unit, so focus on delivery condition: confirm the Sprinter chassis service history and warranty paperwork, and run the diesel through a cold start. Test the items the descriptions actually name, including the heated and power adjustable driver and passenger seats, the rear power sofa bed mechanism, the exterior 110V outlet and the wet bath shower, toilet and sink for leaks. Check seals, storage lockers and tire date codes.

What features come on the Interstate 24GL?

Across the three listings, the recurring highlights are heated driver and passenger seats, with one coach specifying power adjustable heated seats, plus a wet bath, a rear power sofa bed and storage lockers. One listing also notes an exterior 110V outlet. The wet bath is described with a one-piece shower, a riveted aluminum porthole door, a toilet, and a sink with an articulated mirror and towel storage. It is a diesel Class B on a Mercedes-Benz Sprinter 3500 chassis.

Is the Interstate 24GL a good RV for couples?

The listings point that way. It is a compact Class B touring coach on a Sprinter 3500 chassis with a wet bath and a rear power sofa that converts to the bed, which suits two people who want overnight capability without booking a hotel. The descriptions do mention carrying family and friends in comfort for day travel. Beyond that, there is no sleeping capacity or tank data in these listings, so confirm details with the seller.

Where can I find a Interstate 24GL for sale near me?

The three Interstate 24GL listings on US RV Connection are spread across the country: one in Buda, Texas, one in Knoxville, Tennessee, and one in Ramsey, Minnesota. All three are 2026 Class B diesel coaches and all three include photos. With only one unit per metro, expect to travel or arrange delivery unless you happen to be near one of those three cities.

How does the Interstate 24GL compare to the Rangeline RGT or the Basecamp 20X?

The Interstate 24GL is the priciest of the three here, with 3 listings asking $209,995 to $253,540, median $216,877, all 2026. The Rangeline RGT shows 5 listings, all 2026, from $153,722 to $153,995, median $153,951. The Basecamp 20X is a different animal entirely: 8 listings from 2021 to 2026, $39,900 to $74,450, median $67,835. The listings do not include spec comparisons, so judge them on floorplan and price.
