This was another one of the reasons I leapt on the Wiggle deal – no faffing threading long poles through wet tent material ‘tunnels’
You’ll still need a decent area of flat ground that you can get some type of pegs into, and arrange 14 pegs (maybe 10 min?) and 9 poles.
I spent 2 weeks summer camping in Norway, car camping, pitching up at night and gone in the morning. That was with a 5kg 3 man tent. 3 poles and 4 pegs minimum. It was still sometimes tricky to find the right shaped spot at the right time, out of the way yet next to the road/track for getting the stuff from the car.
I camped a bit in Finland too, but by bike and with a hammock. Lots of bare rock, lots of trees, lots of dead wood and non-flat ground between the trees – hammock or small-footprint, self-supporting tents were ideal. And there’s also plenty of Laavu – open shelters. If you’re doing lots of one-nighters, you might end up spending more time in them, and saving the Utgart for longer, pre-planned stops.
Not meaning to rag on your plans, my experience might be completely irrelevant for the places you have planned. Just chucking in my 2p!
