Before starting to tow anything you've got to ask yourself four questions, in order of priority:
1. Is it legal?
To check, you need to know the weight of the caravan and the car manufacturer's towing limits, including the maximum permissibe train weights. You should find details shown on the respective vehicle plates and/or in the owner's handbook.
2. Does my driving licence cover the requirements?
This will normally only be a potential issue if you passed your driving test after the 1st January 1997.
3. If it's legal, it still may not be safe. As a good starting point, the 85% weight ratio recommendation is worth sticking to. (This is max. weight of the caravan divided by the kerbweight of the car)
4. If it's legal and safe, has the car got enough performance to cover my needs?
In your question, you don't say whether you have already checked all the figures and just want an opinion from other owners as to the suitability of your towcar, performancewise. However, if you aren't clear about issues 1 to 3 either, you need to do your homework first.
