I think that the Tent Tipi is meant to be used more in a base camp setup.
Can't really think of lugging in a stove (like in the second picture) on
a backpacking trip, although I could see a small wood fire set in the middle
of the tipi with the smoke going out the top.
I like the amount of head room that you have inside the tipi as opposed
to a tent and think it would be worthwhile in that sense.

Anyway, just my $0.02 on the subject

Cheers
