The difference between a weekend camper and a full-time adventure van starts with one number: interior height. Here is every van platform compared — and why standing room changes everything about how you use the space.
If you are comparing van roof heights for a camper conversion, you are making the most important decision of the entire build. The three dominant platforms — Ford Transit, Mercedes Sprinter, and Ram ProMaster — all offer high roof options with full standing room. But height alone does not make a livable van. What matters is what you do with that space: proper insulation, finished walls and ceiling, ventilation, and a layout that works for how you actually travel. OZK Customs in Fayetteville, Arkansas builds professional interior packages on all three platforms with fixed pricing — every component from the menu, no surprises.
At 48 inches, you are sitting or lying down. At 67 inches, most adults are hunched. At 81 inches (Ford Transit High Roof), you stand upright, cook at a counter, change clothes, and move naturally. Every other build decision flows from this.
High roof vans support overhead cabinets, proper ventilation fans, ceiling-mounted heaters, and lighting that does not blind you in bed. Low roof means compromises on storage, airflow, and comfort.
A high roof gives you room to insulate properly — 1 to 2 inches of closed-cell foam on walls and ceiling — without losing headroom. Low roof vans force you to choose between insulation and comfort.
81 inches of interior height. The most popular platform for professional van builds. Best value, easiest service network in the US.
78 inches of interior height. Premium ride quality, available factory 4x4. The choice for highway comfort and long-distance travel.
76 inches of interior height. Widest interior floor of the three — more usable floor space for creative layouts despite slightly lower ceiling.
Our interior packages include proper insulation that maintains headroom. Closed-cell foam, vapor barriers, and finished walls — no exposed metal, no condensation dripping on your bed.
The Ford Transit High Roof has approximately 81 inches of interior height — the tallest of the three most popular cargo van platforms. The Sprinter High Roof is approximately 78 inches and the ProMaster High Roof approximately 76 inches.
Yes — if you choose a high roof model. Ford Transit, Mercedes Sprinter, and Ram ProMaster all offer high roof options with 76-81 inches of standing room. Standard and mid-roof models do not allow standing for most adults.
High roof vans are taller but drive like a normal vehicle on the highway. The main consideration is parking garage clearance (most high roof vans are around 9 feet 6 inches tall) and slightly more wind sensitivity. Most owners adapt within the first day.
OZK Customs uses a fixed pricing menu for all interior work. An interior base package covers insulation, walls, ceiling, and flooring. You configure additional systems based on how you travel. No hourly rates, no change orders.
