I think everyone is aware that all aluminum stakes are not created equal. There are quite a few different designs an alloys. I usually buy a variety of designs as I find them useful in different situations such as sand, clay, loose gravel etc. And of course there are different alloys of aluminum, some not much better/stronger than a k-bob skewer. I did choose my tent (discontinued when I bought it lightly used) for it's ability to freestand without staking at times. I often camp on river gravel bars where no stake will hold. I used small nylon bags filled with rocks/gravel/sand to secure the fly. Unsecured, it lies against the tent and doesn't do it's job in rain or. more frequently, heavy morning dew from river mist.
I've seen some add-on vestibules made for some tents and have toyed with the idea of getting one for my tent, a common four pole dome shape. So far the factory vestibule has sufficed since it is a three season tent. Having been in non-bear habitat for many years, it has been great for overnight storage of my assorted riverbags. Now though I am in mixed bear territory and will have to change my ways of storing foods and cookware. Still it will be an adjustment not being able to cook a meal in the vestibule on a rainy day.
I get the impression that other than a few cottage makers, very few tents are made here in the U.S. any more. Most brands share foreign makers and specify the materials and construction details. Of course like knives, they will make a tent to whatever specs and pricepoint a customer orders. And as with knives, neither the domestic seller nor maker will say just who is who in the zoo.
