Non-Stop Adventuring
Built in 2021, Marathon is a Sprinter 170 built for a couple and their dog who love to get out to bike, hike, and explore the Pacific Northwest. With a fully stocked kitchen, dinette seating with a dog bowl holder that seamlessly slides into a bed platform, a cozy removable three panel bed, overhead storage, and plenty of space in the rear garage area, this is the perfect basecamp for any adventure.
To keep everything powered off-grid, our team installed a 400Ah lithium ion power system, paired with a 2000W inverter, 130W of solar on the roof, and a secondary alternator that directly charges the house batteries while the engine’s running. The 30 gallon freshwater tank provides cold and hot water to the rear shower and sink, thanks to the Espar diesel hydronic heating system and the Webasto heater provides warm cabin air at the touch of a button.
