ProMaster Van Interior: Layouts, Design & Build Options

What Makes the ProMaster Interior Different From Other Vans?

At 6'4" between the wheel wells, the RAM ProMaster is the widest cargo van available in North America. For comparison, the Mercedes Sprinter measures 5'8" and the Ford Transit comes in around 5'10" at the same point.

Those extra 8 inches don't sound like much on paper, but they change everything about what you can fit inside. Layouts that require awkward compromises in a Sprinter just... work in a ProMaster. We build across all three platforms at our San Diego, CA shop, and the ProMaster consistently opens up options that narrower vans can't match.

What Can You Fit in a 6'4" Wide Van Interior?

Here's how the ProMaster's width changes the most common interior decisions:

• • East-west bed placement: A queen-size mattress (60") fits sideways across the van with room to spare. In a Sprinter, this is a tight squeeze. In a ProMaster, it's comfortable — and you keep the aisle clear during the day.
• • Side-by-side galley and bathroom: You can put the kitchen on one side and a bathroom enclosure on the other without eating all your living space. This is one of the most requested layouts we build.
• • Wider countertops: An extra few inches of counter depth makes a real difference when you're cooking every day. Chopping, prepping, and cleaning all feel less cramped.
• • More storage options: Deeper overhead cabinets, wider under-bed storage, and room for full-size drawers instead of narrow cubbies.

How Does ProMaster Wheelbase Length Affect Interior Space?

The wheelbase you choose determines how much room you have to work with. Here's how the three ProMaster lengths compare for interior builds:

What Cabinetry and Storage Options Work in a ProMaster?

Good cabinetry is where a professional conversion really separates itself from a DIY build. We build all our cabinets custom to the specific van and layout — no off-the-shelf boxes crammed into place.

• • Overhead cabinets: The ProMaster's width lets us build deeper overheads that actually hold things. Soft-close hinges are standard on all our builds.
• • Under-bed storage: With a raised fixed bed, you get a huge garage underneath. We add slide-out drawers, pull-out trays, or open access depending on what you carry.
• • Kitchen cabinetry: Pull-out drawers, spice racks, trash bins, and utensil organizers. We design these around how you actually cook.
• • Material options: Baltic birch plywood is our go-to for most builds. Premium builds can use walnut, oak, or other hardwoods for a more refined look.

What Kitchen Options Are Available in a ProMaster Van?

The kitchen is the heart of most van builds. In a ProMaster, you have room for a layout that actually works for daily cooking — not just heating up canned food.

• • Cooktop: Two-burner propane, induction, or a combination. Induction requires more electrical capacity but keeps things cleaner.
• • Fridge: 12V compressor fridge (Dometic, Isotherm, or Vitrifrigo). Sizes range from 50L to 130L depending on your space and eating habits.
• • Sink: Stainless steel undermount is most popular. Bar-size or full-size depending on counter space.
• • Countertop: Butcher block, solid surface, or stone. Each has weight, durability, and cost trade-offs.
