I have a 2012 Forest River Solera with a power awning (Dometic/A&E 9100 series) which measures 15ft 6in from center arm to center arm. Would love to get a screen room for longer trips/stays, but I'm not sure what size would be best, recommendations on brand, and experience with windy conditions. As usual, I could use all the help I can get from experienced RVers - Thanks in advance!!
