# Motorhome on Eurotunnel & Channel ferries: height & gas (2026)

> Two things decide a motorhome's Channel crossing: your rig's true travelling height (which sets the carriage and the price band) and your gas (declare it, switch it off). LeShuttle (Eurotunnel) carries vehicles up to 4.2 m high and 18 m long — anything over 1.85 m rides the single-deck carriages — but refuses vehicles propelled by LPG (liquefied petroleum gas), while allowing the cooking/heating cylinders most motorhomes carry (47 kg per cylinder, 50 kg total, switched off). Ferries (DFDS, P&O, Irish Ferries) band by height and length — some from as low as 2.25 m — and allow up to three cylinders (47 kg total), turned off and declared.

## TL;DR

- **Measure your true height.** On flat ground, including roof box, satellite dome, air-con pod, and aerial; count rear bikes toward length. Book the band that matches — under-declaring risks a later sailing or a top-up charge at the port.
- **LeShuttle — generous on size, strict on LPG fuel.** Carries up to 4.2 m high / 18 m long (over 1.85 m = single-deck). Refuses vehicles *propelled* by LPG. Domestic cooking/heating gas is fine: 47 kg per cylinder, 50 kg total, fixed tanks under 80%, switched off and declared.
- **Ferries band by height & length.** DFDS up to 4 m (length bands ~7 / 10 / 12 m); Irish Ferries splits at 2.25 m; P&O around 2.3 m / 6 m before you contact the freight team. A tall rig can pay more by sea than through the tunnel.
- **Gas: declare it, turn it off.** Every operator: up to 3 cylinders / 47 kg total, shut off at the valve and secured for the crossing, declared at check-in. Passengers can't stay on the vehicle deck under way anyway.

## Measure your true height first

Every operator classes a motorhome by **size band**, so the crossing starts with an honest tape measure. The figure that matters is your **real travelling height and length** — not the brochure number.

- **Height:** measure on flat, level ground to the highest fixed point — and add anything mounted up top: a **roof box**, **satellite dome**, air-conditioning pod, or aerial.
- **Length:** include a **rear bike rack** and the bikes on it, plus a tow-bar or A-frame. Several operators price by length as well as height.
- **Book by the real number:** declaring a band too small risks being moved to a later departure or charged the difference at check-in. It isn't a fine — it's a space-and-safety allocation, so the manifest has to match the vehicle.

Knowing your rig's exact profile is the same habit that keeps you off low bridges and out of tight lanes — see [motorhome dimensions for navigation](https://rovee.io/topic/motorhome-dimensions-for-navigation/) for how to record height, length, width, and weight once and use them everywhere.

## LeShuttle (Eurotunnel): size & the LPG rule

The tunnel is the **most generous on height** of the Channel options, and the fastest (about 35 minutes). Vehicles over 1.85 m ride in the taller **single-deck carriages**, so a tall motorhome is routine.

- **Maximum size:** up to **4.2 m high**, **18 m long** (vehicle plus caravan or trailer combined), and **2.55 m wide** (excluding mirrors).
- **The LPG distinction — the one to get right:** LeShuttle **refuses any vehicle propelled by LPG** or another flammable gas, even as a secondary fuel. That's about the *engine*. The **gas you cook and heat with is allowed**: domestic cylinders and fixed habitation tanks travel, within limits.
- **The cooking/heating gas limits:** up to **47 kg per cylinder**, **50 kg total** per vehicle, fixed tanks **under 80% full**, all **switched off** and **declared** at check-in, where staff inspect them. **LNG, CNG** (liquefied and compressed natural gas) and **hydrogen** are refused.

So the practical read: a normal coach-built motorhome with a gas locker crosses without fuss; only a van whose *engine* runs on LPG is turned away. If that's you, a ferry is the alternative.

## The ferries: height & length bands

The three lines a motorhome is most likely to book price by **height and length band**. A tall rig that sails freely through the tunnel can sit in a higher-priced band at sea, so it's worth comparing.

| Operator | Height | Length bands | Above the band |
| --- | --- | --- | --- |
| LeShuttle (tunnel) | Up to 4.2 m (over 1.85 m = single-deck) | Up to 18 m combined | — |
| DFDS | Up to 4 m | ≈ 7 m / 10 m / 12 m | Freight for longer |
| Irish Ferries | ≤ 2.25 m, then a higher band | < 8 m / 8–12 m | Freight over 12 m |
| P&O Ferries | ≈ up to 2.3 m standard | Up to ≈ 6 m | Contact the freight team |

Bands and fares move with the season and the route, and the P&O figures above were the hardest to confirm from the operator directly — always check the exact band on the operator's own booking tool before you pay. All of them count **roof items in the height** and **rear racks in the length**.

## Gas on board: the rule that travels

Across every operator, the gas rule is essentially the same, and it's a **maritime safety** rule rather than an operator quirk: **declare your cylinders, shut the gas off at the valve, and secure the bottles** for the crossing. Passengers can't remain on the vehicle deck while the ship is under way, so nothing needs to be running.

| Operator | Cylinders / weight | Key rule |
| --- | --- | --- |
| LeShuttle | 47 kg per cylinder · 50 kg total (tanks < 80%) | Off, declared, inspected; LPG-*propelled* vehicles refused |
| DFDS | Up to 3 · 47 kg combined | One may stay connected (e.g. fridge); rest off; declared |
| Irish Ferries | Up to 3 · 47 kg combined | Closed & secured away from heat; declared; no spare fuel cans |
| P&O Ferries | ≈ 3 · 47 kg combined | Off, secured, and declared (confirm current terms with P&O) |

The gas you refill on the far side is a separate question with its own country quirks — see [motorhome LPG in Europe](https://rovee.io/topic/motorhome-lpg-adapters-europe/) for the four fill adapters and which one each country uses.

## FAQ

### Can I take an LPG motorhome through the Eurotunnel?

Draw the distinction carefully. LeShuttle refuses vehicles that are *propelled* by LPG (liquefied petroleum gas) or another flammable gas, even as a secondary fuel — an LPG-conversion engine won't be carried. But the LPG most motorhomes use for cooking and heating is fine: domestic gas cylinders and fixed habitation tanks are allowed within limits — up to 47 kg per cylinder, 50 kg total per vehicle, fixed tanks under 80% full, all switched off and declared at check-in, where they're inspected. So a normal coach-built motorhome with a gas locker travels without a problem; a van running its engine on LPG does not.

### How do I measure my motorhome for a ferry or the tunnel?

Measure the real travelling height and length, on flat ground, including everything that sticks out: a roof box, satellite dome, air-conditioning pod, aerial, and any bikes on a rear rack (which add to length). Operators class you by band — LeShuttle carries up to 4.2 m high and 18 m long (combined with a trailer); the ferries band by height and length, some as low as 2.25 m before a higher price. Book the band that matches your true measurement.

### Do I have to turn the gas off on the crossing?

Yes, on every operator. The common rule is to declare your gas at check-in and have the supply shut off at the cylinder valve for the whole crossing, with the bottles secured against the ship's movement. DFDS lets one cylinder stay connected to a running appliance such as the fridge; the rest are off. Passengers can't stay on the vehicle deck while the ship is under way in any case. It's standard maritime safety, not an operator quirk.

### Which is better for a tall motorhome — the tunnel or a ferry?

For height, LeShuttle is the most generous: it takes vehicles up to 4.2 m, so a tall A-class or a rig with a roof box rarely troubles it (over 1.85 m simply rides the single-deck carriages). The ferries carry tall motorhomes too — DFDS up to 4 m — but several price by height above about 2.25–2.3 m, so a tall rig can cost more by sea. The trade-off is time and preference: the tunnel is ~35 minutes; a ferry is a longer crossing with decks and food. Book by your real dimensions either way.
