I need some help getting this screen room installed. The initial setup is pretty obvious using the awning poles and a bit ov Velcro, but when it get to the camper itself I hav no idea how to connect the elastic loops since there are no apparent anchor points. Also, am I supposed to add Velcro directly to the canvas? Doesn’t seem right. Can’t find anything online about this particular model. Any advice and/or help would be greatly appreciated.
