The Ultimate Off-Grid Adventure Rig – [Coming Soon] Promaster 2500

The Chassis: 2020 Ram Promaster 2500 (159”) – 72,000 miles, Fully Inspected. The Build: Currently in progress at Whitewater Vans (Broomfield, CO). Target Completion: April 1st (4/1/26).

We are currently building our latest high-capacity adventure rig. This van is designed for the serious traveler who needs off-grid power, internal water systems, and a beautiful layout that doesn't feel cramped.

Note on Images: Photos 1–3 are AI-generated design concepts and inspiration from another van to show the intended layout and aesthetic. Photos 4–6 show the actual chassis in our shop and examples of our previous finished work.

1. Massive Electrical: 6kWh (450Ah) Lithium system. 3000W Inverter. This rig is designed to run induction cooktops, water heaters, and tech gear without a second thought.
2. Off-Grid Water: 33 Gallons of fresh water (all internal to prevent freezing) + 4 Gallons of hot water on demand.
3. Rear Spray Dock: Hot/cold exterior shower/wash station at the rear doors.
4. The "Garage": A massive rear cargo area designed for bikes, skis, and heavy gear under a comfortable fixed platform bed.
5. Chef’s Galley: Hot/cold water at the sink with high-end fixtures and deep-basin stainless steel.

Because we are mid-build, the buyer has a unique 20-day window to customize the final aesthetic of the van. If you put down a deposit soon, you can choose:

1. Cabinetry Colors.
2. Countertop Finishes.
3. Solar Add-ons (The system is pre-wired and ready for panels).
4. Air Conditioner (The system is pre-wired for A/C)

1. Skip the Queue: Our custom build slots are usually booked 4-6 months out.
2. Get Your Inputs: Get the "custom" feel without the "custom" wait time.
3. Transparency: We invite serious buyers to the shop in Broomfield to see the "bones" of the build before the walls go up.
