You can force the Austrian cookset down into the windshield for carrying - no big deal. To be honest though I prefer the full SAT to the hybrid one shown here - the extra pan is nice but I don't tend to use it. Maybe if you're cooking for two it would be useful - each can have his own bowl for stew/soup etc. Or you can use one as a cup, and have a brew while the other acts as a lid to the main billy-can.
Don't worry about using the windshield as a woodburner - its true it turns a nice coppery colour - pretty! - and gets a bit softer, but I've used mine umpteen times and its still perfectly functional. I know many people like the stainless version, and I have one of those as well, but still normally use the aluminium one. It seems to cook a bit better - better spread of heat I presume - and is still very solid. This is no thin bit of kit!
