[VAC] Dumb Screen Room Question

["Elisa" <vxn@xxxxxxx>]

Hi,
I'm back on the List again for awhile and have a question:  what supports
the side walls of a screen room along the top edge?  The side attaches with
snaps to the trailer body and to the front screen wall with the corner
zippers at either end of the awning.  But I don't know how to eliminate the
sag along those side top wall edges - should a pole run through it from the
awning to the trailer somehow?  I have two poles that I have no idea what to
do with - do they support the awning vertically at each end of the awning?
My trailer is a 28 foot Argosy with a full length awning and came with a
screen room, which I just tried to put together on a trip this past week.
Thanks,
Elisa
