We have just taken delivery of a 2012 Lunar Delta TI. In the owners manual it gives the size of the awning as 1075. The awning we chose, an Isabella Commodor Concept (that was delivered with the van) measures 1050. When we enquired, the dealer said this is the size Isabella says fits this model of caravan. We will not be erecting it until the end of May, for the season, so it remains packed. What would you do?
