Thanks for that Phat , on behalf of Becky not myself...
As you probably know I am with Tarptent however we don't have an expedition type shelter , the kind required "on places like McKinley".
Reading between the lines I got the impression that Becky is not in fact going to Denali but wants a somewhat safe enough shelter for something like that.
If Becky had stated that she was in fact going up there I would have strongly suggested to do a few excursions in much easier areas first then attempted to go up there with a guided group (tents provided) because if someone is not aware of the type needed up there they certainly should not be anywhere nearby by themselves or outside an organised expedition.
