We have an Autocruise Stargazer 2006 and have just purchased an Outdoor Revolution Movelite XLF driveaway awning. We also purchased the Fiamma fixing kit to attach it to the windout awning on the van. We came across a problem with the tunnel. If we attach it so that the roof of the tunnel is taut then the side walls don't reach the side of the van. Conversely if we attach it so the side walls come up to the van, we are left with the tunnel roof flapping about with too much material! Any suggestions please?
