We have a 2015 AF 990 with the rear awning & no side awning. We are not big awning folks & rarely use it. Had a manual one on the last camper but thought I would use an electric one more but so far haven't done it, but that could possibly change.
I saw a guy once put up a light weight tarp to sit under. He put it up so one side was 6 ft off the ground & the opposite side was 1 or 2 ft off the ground. He used 2 poles in the front side & guyed them with ropes & stakes, the back was held by long ropes tied to stakes that were far enough away from the tarp to keep the back of the tarp a foot or two off the ground. I thought it was pretty neat & I hung out there with him, keeping out of the sun.
