I took a 4 man to a small island off Prince of Wales in SE Alaska last September. As I stated, with the small stove, it is tight for 2 guys and gear and I could not stand up completely in it. Still worked just fine for what we needed. You can't haul an Alaknak in a Super Cub. Well you can, but that costs an extra trip...
I was very glad to have the stove and was so impressed with how the tipi held up to the never ending rain, I don't believe I will ever be without one! The liner is a necessity IMO. A friend has a TiGoat tipi and the lack of a liner kept me from purchasing that system.
This is my buddy wondering if the cener pole is going to hold during one of the storms we spent in the tipi with 50 knot sustained winds. This is how I spent the time...
No worries. Dry and cozy with a little fire in the stove.
I kept the stove, sold the 4man, and bought a Super Tarp and Annex for solo trips along with an 8man and large stove for base camp setups with a partner or two.
These units have been to Everest and back. They are well thought out and engineered. Over engineered actually. They are expensive, but I learned a long time ago expensive pays for itself over the long run.
