Make sure the caravan is not to close to your max towing capacity as you will then put all your pruck and kit in the van and substantially increase its weight.
If you have never towed before I would recommend getting a lesson or two from a trailer training company, explain your situation and hopefully they will not have a silly car and small trailer to train you in. You want to take a lesson or two in a combo with a substantial trailer. This is not a requirement but a common sense idea.

As well is two words!
How does a sage know everything about everything? or does he? or does he just think he does?
