I guess it’s a case by case/preference thing.
My case is, multiple riders put up for the winter, in an open flame heated building.
I store what little fuel is left, in my unheated, garden shed.
Motorcycles & Minibikes with venting fuel tanks do not share the same space with me & the kerosene heaters.
The steel tanks aren’t going to rust away, by fall.
I run QD’s on my fuel lines, to make draining easy, as they ride in the van with me, during the warmer months, as well.
