Most all year motorhomers and ralliers use propane rather than butane to save messing about in cold weather.
Flow is reduced as temperature lowers not always down to freezing and could give the impression of an empty cylinder.
There is not a lot of difference in performance between the two and you shouldnt notice any difference. Before the pro butane brigade come back arguing, if I have to I should be able to show you figures as I spent my working life in the compressed/idustrial gas business and I probably still have tech data sheets about somewhere.
