A few years ago you weren't able to take a motorhome on the tunnel if it had a gas tank on board. This rule has now been relaxed but a number of key conditions do remain.
In response to these many queries, I have prepared the following:
LPG. Vehicles fitted with LPG containers to power domestic services e.g.
cooking, refrigeration, heating and water heaters are accepted as long as the
containers are switched off, weigh no more than 47kg and are not more than 80%
full. If your vehicle is fitted with such a container, you must declare this at
Check-In.
LPG (Liquefied Petroleum Gas) and dual powered vehicles (i.e. vehicles fitted
with an LPG tank as an alternative fuel) cannot be accepted for transport by
Eurotunnel.

How many litres of gas are in 47kg? 91.8 litres.

The standard Concorde Tank is 120 Litres capacity, so 80% of capacity is 96
litres. The important figure, the lowest of the two conditions is therefore the
maximum weight condition, 47Kg or 91.8 litres of LPG.
Customers using the tunnel in their Concorde are therefore not allowed to fill
any more than 91.8 litres. We therefore suggest 90 litres as this is well less
than 80% capacity maximum limit (96 litres) and less than the 47Kg maximum limit
(91.8 litres)
It should be noted that with the 120l tank it is almost impossible to put in
more than 90 litres in the tank anyway as it is designed to cut off at about 80%
pressure. I think the most I've ever put in a 120 litre tank is 92 litres.
