I think some of you are missing an important consideration.
Tents get wet, and often you'll pack them wet. You try to hang out until they totally dry, and you won't be hitting the road until noon some days. And some days, when its foggy or raining, they won't dry at all.
I wouldn't want to pack anything wet inside my cases where I'm trying to keep everything else dry.
I carry my tent in a separate tent bag, strapped to the outside of the bike. I use the Helen's 2 Wheel medium cord-close sack
Cord Close Sacks
Its made by a motorcycle rider, for strapping to motorcycles - much better than just a tent sack designed for strapping to a backpack. So the tent can be stuffed into this thing wet or dry. I just ordered a replacement for the one I used the past 5 years (sun does that to nylon, as you know).
So, I'm not sure why any of you would want to carry a tent inside your cases. And buying a tent, simply because it will fit inside your cases, is also a bad way to choose a tent. Buy a tent because its suitable for the job of keeping you dry, holding you and all your gear, easy to set up, light-weight, compact, all the other stuff - but not because it can fit inside your sidecase.
