Vans made BEFORE 2012:
If you have a pre-2012 van - You can not purchase ONLY the walls.
You need to buy the complete package of a new bagged awning and walls.
This is because Jayco has resized and redesigned the bagged awnings from 2012.
So your old bagged awning will not fit the new walls.
You will need to buy the complete package of a bagged awning and walls.
If you buy the package of an awning and walls this will be able to be retrofitted to your older van.
If your old bagged awning is in good condition you could consider buying the package and putting the old bagged awning on the offside of your van as an additional shade area.
