Kinda hard to show this with pics. Sorry.
There are few pics in other discussions, where the hoop is sandwiched in the folded mattress, and others where the hoop is set on top of the folded mattress - in either case, my strap comes undone - the snap simply does not hold up. I was thinking maybe a 12 inch length of wide velcro would do better - I may try it.
On the other hand, the bulk inside is no big deal - as I do stuff the tenting well back to have a good seal on the door.
I guess it bugs me more than anything else - as I think as a new unit it would hold better. I am stickler with some details
Regards,
Denis
