I've spent a fair bit of time in wall tents (Montana Canvas, Reliable, etc), and they're awesome. I've heard the Kodiak tents are well made, though I haven't used one. But I prefer an internal frame - in my experience they tend to be sturdier. On the other hand, they also tend to be more expensive. Also, last time I looked, the Kodiak tents don't include a stove flap, so you'd have to have one sewn in, if you're want to use it with a wood stove (and I'd recommend at least having the option).
Last year, I decided I wanted to buy my own outfitter tent. I did a bunch of homework on various options, but I kept getting back to the fact that they are
really heavy. Which is fine if all you're doing is car camping or horsepacking to a camp, but other than that, they're pretty limiting. For that reason, I ended up getting a
Seek Outside 6-person tipi w/woodstove instead. The entire setup,
with stove, is less than 10 lbs, and has 150 sq. ft. of space. It's really well made, and I can take it just about anywhere.
In the end, I think it really just comes down to what you want to do with it. If weight isn't a concern, then a traditional wall tent, like the Kodiak, etc. is great. And if most of your camping is going to be in mellower weather, I'm sure the external frame is fine. Good luck with your decision, and let us know what you end up getting!
