Now that I have the rain fly squared away, has anyone added a bag awning track to either the side or rear of the flip pac and if so, did you bolt all the way thru to the interior or just into the side/back wall. I'm thinking of putting a track on both sides and rear so that I have the option of erecting it on either side or back. Searched the past threads and didn't really see my answer. Going to buy a 6' bag awning. They seem to be relatively cheap, around $200.00. thx
