What your van’s size and weight cost you every month: tolls, ferries, pitches, fuel

Three numbers on the van’s spec sheet — height over 2.00 m, length over 6.00 m, plated mass over 3,500 kg — each move you into a more expensive class of toll, ferry or pitch, for every month you own it. The monthly budgets everyone publishes (2026 diaries put two adults in Europe at roughly €820–1,500 a month, €900–1,100 typical) are honest about fuel, sites and food, and silent about this, because their van was already bought. This post is the part before that: the running cost your choice of body sets, with every base van in the planner sorted against the three thresholds.

None of the deltas below are as large as fuel. All of them are permanent, and two of them (height and mass) are invisible on a test drive.

Threshold 1: 2.00 m tall — the toll class you drive in

French motorways price by height: class 1 is a vehicle up to 2 m high and 3.5 t; class 2 is 2–3 m high at the same mass, and costs roughly one and a half times class 1 on the same stretch. Spain and Portugal use similar height or axle-height steps; Italy puts nearly every van in class B whatever its mass. So the question is simply: is your van under 2 m?

Exterior heights are manufacturer figures from the planner’s van database, unladen and without a roof fan or solar frame — a 5 cm fan cowl on a 1.99 m Transporter puts it over the line at the barrier. Note what the left column is: every van in it is a sit-down van. Standing height and the car toll class are mutually exclusive; that is the actual trade.

Threshold 2: 3,500 kg — the regime you drive under

The licence consequence of uprating past 3.5 t is well known. The running-cost consequences are less so:

• France: over 3.5 t on two axles is class 3 — roughly double class 1.
• Austria: up to 3.5 t you buy a vignette; over it you carry a GO-Box and pay per kilometre, a different order of cost.
• Switzerland: up to 3.5 t the annual vignette; over it the heavy-vehicle charge, paid per day in the country.
• Germany: no toll for motorhomes at any mass — the one place the threshold is free.
• Speed limits drop on motorways in several countries above 3.5 t, which is fuel and time, and some city centres and bridges are signed against it.

Which bodies stay under after a real conversion is a table of its own — the under-3.5 t ranking shows a Ducato L3H2 keeps ~650 kg free after a 600 kg build, a Sprinter L3H2 330, a Daily L5H3 48. Buying a van with 500 kg of headroom is how you never meet this threshold.

Threshold 3: 6.00 and 7.00 m — ferries and pitches

Ferry operators price vehicles in length bands, and 6 m is the common first break (7 m the next), usually with a separate step for height above ~1.85–2 m. Many campsites charge a long-vehicle supplement at 6 or 7 m, and a share of municipal aires and city car parks post a 6 m or 7 m limit outright. Here is where the planner’s bodies fall:

The Ducato L3 at 5.998 m is the whole reason that body dominates European conversions: 3.71 m of cargo floor in a sub-6 m vehicle. It is also 2 mm from the line — a towbar or a rear bike rack is measured, and moves it. The Sprinter L3 (6.97 m) and Crafter L4 (6.84 m) buy 60 cm more floor than the Ducato L3 for a band step on every crossing; the length guide is where that trade is argued out.

Mass and fuel: real, but the smallest of the four

A heavier van burns more, roughly 0.3 L per 100 km for each extra 100 kg in mixed driving (more in towns, less on the motorway) — a rule of thumb, not a measurement. Across the 300 kg that separates a Ducato L3H2 (2,095 kg kerb) from a Sprinter L3H2 (2,405 kg), at 1,500 km a month and 2026 diesel at €1.50–2.00 a litre, that is about 13 L, or €20–27 a month. Real, permanent, and less than one motorway day in the wrong toll class. Build weight works the same way, which is one more reason the 600 kg build beats the 900 kg one.

Reading the three together

• Under 2 m, under 6 m, under 3.5 t — the mid-size low roofs (Vito, Expert, Trafic H1, Transporter H1). The cheapest vehicles to run in Europe, and you cannot stand up in any of them.
• Over 2 m, under 6 m, under 3.5 t — Ducato L2/L3, Transit L2/L3, Crafter L3, Sprinter L2, Master L2. One toll class up, ferry and pitch bands untouched, licence B. This is the sweet spot, and the Ducato L3H2 is its centre.
• Over 6 m — you pay a band step on every crossing and some sites, and on the long RWD bodies the 3.5 t line is close enough that a family build crosses the third threshold too.

The diary numbers stay the diary numbers: what you drive, where you sleep. But the class you do it in is set once, on the spec sheet, and the planner shows the three figures — exterior height, exterior length, plated mass minus your build — for every variant before you buy it.
