I spoke with a Lippert tech and confirmed that you'd be able to go with the Solera RV Slide-Out Awning - 8'1" Wide - 48" Projection - White Item # LCV000163289 as long as you had the clearance for the arms. The Arms are going to stick out approximately 7 or 8 inches on both sides past the flange. If you do not have the clearance then the # LCV000163288 is the correct size for your slide-out. view full answer...
