Ground sheet of new 2016 Fleetline GS smaller tent

We took delivery of our new Jurgens Fleetline GS 2016 caravan yesterday (6/7/2016) We have been campers for over 20 years. Over the years, the caravans just got more and more expensive, with less accessories. The groundsheets for the tents were always standard and at least 0,5 m wider on each side of the tent. Now on the new expensive caravan, the ground sheet is 2.2m x 4.8m and barely covers the inside of the tent. On enquiry at the dealership where we got a very good deal, they said that it is a standard issue that comes from the factory. They cannot do anything about it and we have to buy an additional, bigger ground sheet, if a bigger ground sheet than the tent is required. I really feel that paying over R200 000 for a caravan, the standard ground sheet issued with the caravan should at least cover the full inside of the tent, which is currently not the case.
