In today's RV market, where personalization and practicality are increasingly valued, the Dachi Mars 300S, with its superior chassis performance, stylish and rugged exterior design, and user-friendly configuration details, has become an ideal choice for many RV enthusiasts. This model, with an official guide price of 449,800 yuan, is based on the core concept of "reliability for peace of mind, and full configuration for even greater value," incorporating the wisdom of hundreds of RV enthusiasts to create a mobile home that combines off-road performance with comfortable living.

The Dachi Mars 300S features straight, square body lines and an integrated flat roof design, eliminating the risk of leaks and providing ample space for solar panel installation. The fastback styling not only reduces wind resistance and improves driving stability but also gives the vehicle a unique visual identity.

The vehicle measures 5998×2540×3090mm, strictly controlled within 6 meters, allowing it to be driven with a standard C-class driver's license. The body is constructed of aluminum-plated sandwich composite material, with an embedded high-density XPS insulation layer and a high-strength aluminum alloy cage frame, balancing lightweight design with impact resistance. The body decals are vibrant, corner protectors enhance overall strength, and explosion-proof paint skirts protect against gravel scratches, showcasing a rugged off-road character. A

3.2-meter outdoor awning is located on the right side, with an integrated gravity-fed water inlet and AC power interface for convenient operation. Fixed steps reduce potential points of failure, and the rear-mounted through-type storage compartment is scientifically divided, housing a 70-liter low-temperature water tank for extreme cold environments. The chassis features a near-off-road design, with a 180mm ground clearance easily handling unpaved roads, and a dual-rear tire layout further enhances load-bearing capacity and stability.

Built on a domestically produced Iveco 4.5T chassis, it features a 3.0T diesel engine and a ZF 8AT transmission, delivering 180 horsepower and 430 Nm of torque, providing strong power and smooth shifting. The combination of front ventilated disc brakes and rear disc brakes, along with a multi-link independent suspension and leaf springs, balances handling and comfort. The driver's cabin is equipped with an electronic power steering wheel, LCD instrument panel, electronic parking brake, ESP stability control system, and height limit warning function. Both driver and passenger seats are equipped with airbags and three-point seat belts, providing comprehensive protection for driving safety. The
living area features a layout of a cab-over bed, a lounge area, a kitchen area, a bathroom, and a rear transverse bed, with a 2.2-meter interior height that avoids a feeling of confinement. A through-cabin window connects to the driver's cab, accommodating up to four people while driving. Light-colored environmentally friendly panels paired with ambient lighting create a warm and homey atmosphere. A wraparound overhead storage cabinet and tiered hanging cabinets meet the storage needs for clothing throughout the year.
