It would be nice if they made those tents adjustable. You can see the huge gap I was talking about in the photo. That's 12 or so inches that could be taken off the height.
For my slider, not much would be gained on the sides, since when the saw is fully up against the fence it matches the tent reasonably close.
If they made a couple different versions addressing the height issue, or made it adjustable (e.g., excess rod could be cut off), they'd sell a lot more of them.
