So, you need help finding your caravan's VIN number?
There are a few places you could look:
1: On your CRiS certificate. on the top right hand corner of your certificate you should see a long 17 digit number starting with "SG"
2: On your VIN plate. The VIN plate is usually located next to the bottom of either corner of the entrance door to your caravan, if it is not here then there should be one on the chassis under the body or on the a-frame. Again, you are looking for a 17 digit number starting "SG"
3: Etched on the corner of your windows
