We don't have the FR awning, but I'll offer another option. Like yours, our camper did not come with the awning. We considered buying it, but we just couldn't bring ourselves spend the $500-600 on it.
We bought a good 10' x 10' EZ Up style awning with a screen room attachment. Below is a pic of how we set it up...minus the screen room. We have the corners tied down using adjustable cinch straps. Three straps are hooked to dog tie-out augers, and one is hooked to the camper's left step housing. The awning just flat out doesn't budge.
It might seem to some like a bit of overkill on securing it down. We've seen freak storms blow through, and have even lost an awning to one...with the storm coming through so quickly that there was no time to drop the awning. We had one blow through this past October, and while everyone else was either chasing their EZ Ups, holding down their awnings, or wondering how much it was going to cost to fix the fresh hole in their roof
, our awning just stayed right where we left it.
To keep from tripping over the augers at night, we have solar lights we plant in the ground between the augers and the poles.
