@Volker64 knowing your preference for rectangular-footprint, and crossing-X poles, the Mountain Hardwear Aspect 2p might be a contender. As we’ve discussed privately, it’s not my “perfect” tent for lack of some nicer details, but it does check a lot of boxes. It’s light, rectangular, double-wall, fast to pitch, inner-first pitch, etc. The body is not “fully” mesh, but it’s mostly mesh, and seems to breathe well enough anyway. It has a 41″ peak-height, which is an improvement over the Tungsten 1p. At the real width of 46″ or so, you can fit your 30″ pad inside with plenty of extra room. You would be welcome to borrow it for a trip if you wanted…
While I was slightly disappointed after playing with it (again, for lack of fancy “features”) I still consider it a strong contender for a possible 3P tent purchase in the future.
I always come back to SlingFin too. The Portals & CrossBow are heavier than what we’d want to call ”ultralight,” but they are superior to much of the market in many ways, and have outstanding features that make them extremely versatile. (If not expensive, once kitted-out…)
The other tent that comes to mind, is the Big Agnes Tigerwall 2p. White not free-standing, nor rectangular floor, it stays well under 3lbs, and offers a 52/42″ width, and meets your minimum 39″ peak-height, with a big wide brow pole. It’s biggest “fault” that I can see, is that it uses a lot more fabric vs. mesh, than what you would prefer. REI still shows having the Dyneema/Carbon version in-stock, if you really wanted to roll the dice on durability, in exchange for minimum weight…
There are also the front-entry, semi-freestanding tents too, but I will not discuss those options at the moment, as I don’t think you’re interested in a front-entry tent, preferring to stay with side-entry designs.
