I can understand the desire to haul a load of kit on a Pulk but as its your first experience 'up there' I'd go the cabin route with one or two nights in tent/tarp not far from the safety of a cabin.
I've never been to the Arctic but have done a lot of UK winter camping; 'hot tenting' I've done but as Fishy said keeping a stove 'in' all night can be a pain in the ass. Concentrate on buying
the very best sleeping bag you afford which will keep you warm all night after the stove has gone out...an undisturbed nights sleep charges your batteries and don't forget to fill a thermos before sleep time...that warm sweet drink first thing in the morning from the comfort of your sleeping bag is wonderful
