I’m going to suggest going a different direction. Hilleberg Nallo. The big drawback as compared to a tipi is that you can’t put a stove in, but as far as 4-season tents go, they are the best in the business.
I’ve owned my Hilleberg Nallo for 3 years and have had nothing but great things to say about it. We always camp above tree line when sheep hunting, and this thing will stand up to anything.
