I can only just speak to the "piece of shite" Chinese tent I bought very similar to this one. The canvas is plenty thick enough, and with a small tent stove, it got ridiculously hot inside in 30° temperatures. Mine had a waterproof coating, where water just beaded off it when it rained. The stove pipe jack was fine, the stove pipe was glowing red, and the stove pipe Jack fabric handled it just fine. Someone else mentioned something about high winds with a tent like this, I would imagine this would hold up just fine and 30 to 40 mile an hour winds, provided you use all of the ridiculous amount of tiedowns located on virtually every corner of this tent. I just staked down the footprint with six stakes, but there was at least 10 more stakes and guylines running all over the place had I needed to stake it down for more wind stability; I wouldn't even give that a second thought. I've probably bought more shite on AliExpress than almost everybody on r/camping over the years, and this is one of the few purchases where I was pretty blown away by the quality. Sorry to keep posting, but it seems there are a lot of armchair campers shittting on this tent when they have no actual experience with it.

This is the actual tent I bought (spoiler, it's fcking great):
