I'll pay a bit more every day to have better materials, better made and in the USA.
The overseas stuff is always a ripoff in the end....
i'm sold on floorless for any situation. If no wood, don't carry the stove. Beyond that its no different. Have been in the 4 season tents and its as cold inside them as outside basically IE we had 5 degrees one morning, water bottles frozen solid etc.... coudln't have been much colder with a single wall at all...
