We have realised that the onl reason we are considering an ehu at easter is for a heater - is it worth thinking about a gas one? if so which one? Most of our camping will be in fields at flyball so not electric anyway! We have dogs nad dd who is 10 months - but wouldnt consider having heater on unless dd in bed (travelcot between the 2 beds in trailer tent) and dogs in their crates (under the beds!) would obviously only have in the awning in morning/evening if really cold and we were watching it?? is it a really stupid thing to be considering?
