I toured 12 nights last year with a 1P Marmot Eclipse. Great in good weather. No room for anything other than a sleeping mat, sleeping bag, and 1 person.
Sold it and bought a 2P MSR Hubba hubba. Leaving on a 2 week solo trip with it on Saturday.
For 2 people, I use a 3P MEC Nunatak 4 season tent. Heavier (double weight of Hubba Hubba), but a bomb proof bunker in a storm.
