Somewhere between 1991 and 1998 probably. Is it 4 berth or 5 berth? Does it have a CRIS number etched on the windows? If it has a CRIS number check the tenth digit which should be a letter, W stands for a 1998 model.
If it has no CRIS numbers it is probably pre-1992. As far as I am aware, all (or most) caravans after 1992 had CRIS numbers. Mine is 1992, and mine certainly has.
