Of course if he caravans in the winter………😜😜
well, thats a good point.

I don't know if you about the Achilles' heel of Butane (blue bottle) gas. Its absolutely fine for late spring summer an early autumn use, but if you intend to caravan in temperatures below about 5C, then Butane can cause problems, it can stop vaporising in the cylinder.
Both Butane and Propane work in the same way , the liquified gas inside the cylinder relies on being able to draw heat from it surroundings to boil the liquiufied gas and produce gas vapour to pressurise the cylinder. It's temperature sensitive, and Butane will work down to about 5C but Propane is good to -40C.
The problem is compounded becasue as you use gas it actually cools the cylinder, so with Butane at 5C there may not be enough heat in the atmosphere to replenish the heat used to boil the liquified gas, so the cylinder vapour pressure can drop below atmospheric.
Of you intend to winter caravan, propane is a better bet, and it is still perfectly safe for UK summers.
I suggest getting the butane pigtail , and use your butane cylinder, but when it runs out consider replacing it with Propane, and obviously you would need to refit the Propane pigtail.
