Storyteller Overland Beast Mode

The Beast Mode lineup starts at $252,821 for the 2026 Beast MODE OG trim. The 2026 Beast MODE XO, which adds the BoomBox hardwall full bathroom, is priced at $260,803. Storyteller was running a $10,000 factory rebate on new 2026 MODE vans through July 31, 2026, so it is worth confirming current incentives with a dealer. Storyteller publishes an illustrative financing estimate of around $1,702 to $1,756 per month based on 20 percent down, a 20-year term, and a 7.99 percent APR, but that is not a guaranteed rate or offer.

Forbes tested a Beast Mode over 2,500 miles and concluded, in their words, that if they had the means they would not hesitate to buy one. Jalopnik praised the EVICTUS suspension and 10.5-inch clearance, and RV Travel called it one of the better Class B vans available. The honest answer is that the value case depends on how you plan to use it: if you want a production van that genuinely handles remote terrain, runs appliances off a 16.8 kWh lithium system, and has a full bathroom, there are very few alternatives at any price. If you mostly camp at hookup sites, the off-grid hardware is more than you need.

The OG trim uses a stowable Halo shower and a 2.6-gallon portable cassette toilet, which frees up more GearGarage space and makes it a better fit for gear-heavy trips. The XO trim adds the BoomBox hardwall wet-dry bathroom with a 4.75-gallon cassette toilet, a full-length mirror, a closet rod, and a drying closet, which is a more hotel-like experience. The OG starts at $252,821 and the XO at $260,803 for 2026. Both share the same chassis, power system, suspension, and off-road kit.

Both vans are built on the same Mercedes-Benz Sprinter 144 AWD turbodiesel platform, so the chassis experience is comparable. The Revel starts from around $202,401, comes with a permanent wet bath, and uses a power-lift gear-garage bed. The Beast Mode costs more but counters with the 16.8 kWh M-Power lithium system, which meaningfully outsizes the Revel's battery pack, a more open floor plan, and a more loaded off-road equipment package including the EVICTUS suspension, brush guard, and onboard air compressor. Reviewers generally land on personal preference, but if off-grid power depth is your priority, the Beast Mode has a clear edge.

There is no official fuel economy figure from Mercedes or Storyteller for this build. Forbes recorded approximately 13 mpg over a 2,500-mile real-world test, while Jalopnik observed around 16 mpg in their XO drive. The difference likely reflects driving style, terrain, and load. Plan your trips around the 13 to 16 mpg range and the 24.5-gallon fuel tank, which gives you a realistic range of roughly 300 to 390 miles per fill.

Storyteller covers their own components with a 1-year/15,000-mile limited warranty. The Lithionics battery pack carries a 5-year warranty. The hydronic heat system, AC, refrigerator, and awning are covered for 2 years. The Mercedes-Benz chassis comes with a 3-year/36,000-mile limited warranty, with federal powertrain and emissions coverage extending to 5 years/100,000 miles and Mercedes roadside assistance to 5 years/75,000 miles.

Owner reviews on RVInsider flag a few recurring themes: battery drain when the van sits for one to two or more weeks without a battery tender, occasional electrical gremlins, and frustration with service coordination between Storyteller, the dealer, and Mercedes when something needs attention. On the positive side, owners consistently describe the Beast Mode as having the best build quality of any non-custom Sprinter conversion they have seen. Going in with a battery tender and a clear service contact at your nearest dealer will address the most common complaints.

Class B adventure vans, including the Beast Mode and the Winnebago Revel, are generally cited as depreciation exceptions compared to larger RVs, but real depreciation does happen. A used 2022 Beast Mode 4x4 has been listed at around $137,000, which shows meaningful value loss from original purchase price. There are no hard resale guarantees, and the market shifts with interest rates and inventory. Buying a van you plan to use heavily and potentially list for rental income is a more reliable way to think about the economics than counting on appreciation.
