I have a AT Chieftain, with a Truma gas heater. I have fitted a Truma chimney extender with a mushroom lid as we are going to the 'snow', the extender is in case we have excessive snow on the roof. As my dealer or nobody else seems to know, will it effect the flow of gasses coming out of the chimney and will I be able to use it safley on the go.
