As said, you will need to put one or both of the trolleys on the rear seat (I did it once!). As 124nut says, the boot is made awkward by the way the large roof is stored, which is why I find the boot on a 129 more usable; there isn't as much boot space taken up by the roof.
As a point of interest, if a cab wasn't specced with a windbreak from new, it will have a different boot lining from one that was, although the storage space won't be affected, unless the windbreak is in situ in the specially designed locating channels.
