Kampoos is a great place to stock up on perishables, don't get carried away there are other opportunities to stock up, just more expensive.
If heading to Dawson Replenish in Whitehorse, Dawson is my favorite town in Yukon but they are a little limited on groceries.
Dawson restaurants aren't that expensive enjoy your stay.
If heading to Tok restock there, Whitehorse is a little cheaper.
Fast Eddies is best place to eat, breakfast was great last fall.
Heading South on the Cassiar stock up in Whitehorse least expensive. Watson lake to pickup items you may have forgotten but you will have to back track to the turn off.
Dease Lake fuel and groceries are available expensive, be sure to top off. Next fuel stop Bell II, after that it is a stretch to the next station especially at night.
Once on 16 you aren't in the wilderness and everything is available.
