No need to tacky up your RV with noodles, smoodles and flags.
Go to a big box store and buy some real nice high quality color coordinated sun shade material. Add grommets to it and attach it to your awning arm with double headed brass snaps.
Actually works as a sun shade.:W And you won't be whacking your head on the arms anymore either.
There are also a ton of companies that sell pre made awning end panel sun shades but they are pricey and the stock ones are slanted. In your case you need a straight top one. IMHO making your own out of color coordinated sun shade material would look a whole lot classier.
