I had my first trip away in my caravan last weekend to a dog show in Blackpool which was a complete wash out.We spent our second night watching them tow people off of the site!
We managed to use all of the charge from the battery in around a day and a half so we need a generator as there are no hook ups where we go. But which one? I need basic advice, not too technical please
I have seen one:

is this any good?
The only one really worth having is an Honda i,am afraid
But they are expensive, We have the EU10i which is quiet and does not use too much fuel, useable power around 900 watts ok for battery charging laptops/tv and little else
Before looking at generating electricity I think you should look at what you are using as a battery, even a smallish one, should last more than a couple of days. As the above post says it is worth looking at solar panels, about 60 or 80W should be ample but still look at what you are using 12V for and try to reduce the consumption as cutting consumption is cheaper than generating. Look at led lights, modern 12V TV (Kogan are excellent in my experience and a good price), restricting use of heating system as they use quite a bit of power for fans, pumps and control circuits.
The Honda EU generators are probably the best and the EU10i is probably the quietest you will find but they are expensive. Kippor produce clones of the Honda but I find they make more noise although it may be my imagination as I have one and I try not to use it.
If you still have a high consumption even after trying to reduce it you might have to consider a twin battery setup and a large solar panel. which is more of a long term winter set up when the panels struggle in the lower light levels and you need a bit more storage to prevent batteries becoming completely flat if it is thick cloud for a few days.
I think the order of priority for you is:-
1/ get battery checked out and if it is not a 110A/hr then think about a new one. The biggest one for your battery locker is going to be best.
2/ start to change lighting over to led concentrating on those that you use most and any halogens.
3/ look at getting a low power TV, some draw as little as 20W in use.
4/ 80W solar panel and regulator
5/ second battery and split charge circuit (Sterling Power have some neat devices
6/ if you really have to then look at a good quality generator but be prepared to pay over £1000 for a good one of decent size. Don't be tempted to go for one of the cheapie generators as they are not designed to run electronic devices (including the power supply unit in your caravan). You will need to get an inverter generator that will produce a clean stable supply. You may also find you are not the most popular person about if you run the generator with other caravans nearby.

We are only really camping at dog shows at the moment which have no hook up as they are fields next to the dog show. Everyone else seemed to have a generator so I won't be alone there!! We had a brand new leisure battery for our trip and were powering lights, fridge and water pump off of it. As well as charging my phone and my sons lap top. No tv and no other electrical things. The charge lasted from Thursday night until Saturday morning. Not long :-(
I would not have thought that the fridge would run off the caravan battery on a 92 Swift. Caravans of that era were normally wired to the car via the grey socket and the circuit would only be live if the engine was charging. If it is running off battery I would have expected the fridge to flatten a battery in just a few hours. It is more likely to be the laptop that is pulling the battery down. Are you charging it via 12V socket or via an inverter? While the 12V option is more efficient it will still pull between 20 and 40W for an average laptop and more if DVD drive is in use. Mobile phone charging uses negligible amounts of power but if you are looking to save as much as you can then charge phones on journey to site from car supply and turn phones off at night.
With sensible use of just lights and waterpump I would have estimated over a weeks use off a 110A battery.
