All-New Summit S4 Layout: The Ultimate Family Adventure Van

In the youtube video, you’ll see firsthand how the S4 combines seating for up to 8 passengers with the perfect balance of daily driver, camper, cargo hauler, and off-road warrior. This van is designed to tackle whatever life throws at you, from motorcycles and mountain bikes to surfboards and snowboards. Planning a weekend escape for the whole family (and their friends)? No problem! The Summit S4 has you covered.

With its versatility, this van is an adventure machine like no other in the camper van world.

For this Summit S4 model, we chose to build it on the 2500 170″ wheelbase 4×4 Sprinter van but it is also compatible with the new AWD Sprinter and the 148″ wheelbase extended Ford Transit. We’ve equipped it with the essentials to ensure it’s trail-ready, including 17″ Black Rhino wheels paired with BFG KO2 tires for added clearance and off-road performance. The ride is enhanced by a 4.3 suspension kit from Van Compass, featuring adjustable Falcon shocks and the Rally Struts, making it a smooth experience whether you’re on highways or rugged terrain.

What sets the Summit S4 apart is the interior layout and design, which focuses on spaciousness and of course flexibility. The concept stems from one of our customers who loved the classic Summit S1 but wanted additional features for modern adventures, such as:

• Ample storage space for mountain bikes, skis, and other outdoor gear.
• A large permanent bed, so you don’t have to set up and break down your sleeping area every day.

We incorporated these ideas to create a floor plan that not only preserves the open and simple feel of the Summit series but also adds practical storage solutions and enhanced living features including:

• Factory swivel seats to maximize living space.
• Retractable Amp Research steps for easy access.
• Upper cabinet storage over the cab and galley area, providing room for everything from kitchen supplies to outdoor gear.
• A state-of-the-art control center featuring solar, inverter, and battery monitors all in one compact unit.
• 300Ah Lithium battery and 380 watts of solar power, ensuring plenty of energy for extended off-grid adventures.

Home on the Road: Flexible Sleeping and Storage Solutions

The Summit S4 comfortably sleeps up to four people. The rear platform bed is a nearly king-sized Moab bed, perfect for those who prefer a permanent sleeping solution. This mattress, provided by Roam Rest, guarantees comfort for your overnight stays.

One of the standout features is the sliding sofa/bed from Mobiframe, which seats two passengers with full shoulder harness seat belts and modern car seat attachments. This innovative sofa slides forward to create a spacious gear storage area for long items such as surfboards or paddleboards and also folds out into a bed for two additional sleepers.

No need to miss any home cooked meals, as the S4 offers a galley shelf with recessed dimmable lighting, perfect for storing cups, mugs, and spices. The induction stove boils water quickly, and the removable cutting board and strainer make the larger sink incredibly functional, even for bigger pots and pans. For refrigeration, the S4 comes equipped with the Isotherm Cruise 100 refrigerator.

Tech and Comfort Combined

The S4 comes with an aftermarket stereo system that can be powered by either the van’s battery or the “house battery,” ensuring you can enjoy your music without draining your van. The system includes front and rear speakers and a subwoofer for a premium sound experience, whether you’re parked or on the move.

We also enhanced the van’s soundproofing with DynaMat for quieter rides and incorporated extreme weather insulation to keep you comfortable in any climate, from winter camping trips to summer beach getaways.

With all these features, you may be wondering how we keep everything in place. Field Van is known for creating vans built to handle tough conditions, and the Summit S4 is no exception. Every 2-4 feet, our cabinets are L-bracketed to the van’s frame or metal plates for added stability, ensuring that your interior remains solid even on rough roads. We also use Trunk Liner material to line drawers and cabinets, eliminating rattles, and our proprietary T-mold edging resists scratching and chipping.

Not to mention, we back our vans with an industry-leading 5-year, unlimited-mileage warranty on workmanship, so you can venture off the beaten path with confidence that the Field Van team has you covered.

The Perfect Balance of Adventure and Comfort

With its livable space, versatile storage options, and tough construction, the Summit S4 is an excellent choice for those looking to combine the freedom of the open road with the comforts of home. Whether you’re setting out for a weekend camping trip or an extended cross-country adventure, this van will be your reliable companion, designed to meet the demands of outdoor exploration while providing a comfortable space to unwind at the end of the day.
