There are a number of reasons why you should keep your caravan well maintained, even if you haven't owned it from brand new.
For one, it can make the van much easier and safer to tow; for two, it can save you petrol (and with prices the way they are these days, this is always a bonus); and for three, they can reduce your chances of experiencing breakdowns or problems whilst holidaying.
Try using these maintenance tips for prolonging the life of your caravan:

• Correct tyre pressure = saving money Did you know that, by keeping your caravan tyres at the correct pressure, you can actually reduce the amount of petrol you use when towing? This is because your car has to exert more pulling force when the tyre pressure is low.
  To check your recommended tyre pressure, consult your caravan manual.
  
• 20 cents is all you need to check your tyres Did you know that you can check the amount of tread on your tyres by sticking a 20 cent coin into the gaps? If you can see the border around the edge of the coin, you really need to replace your tyres.
  Driving with little to no tread can be extremely dangerous, especially on a caravan.
  
• Lights are your nighttime eyes Before embarking on a trip, you should always check that your caravan's lights are working correctly.
  This not only includes your brake, reverse and indicator lights, but also your interior lights.
  Wouldn't you hate to arrive at your destination only to find you cannot see?
• Safety checks could save your life Most caravans are fitted with appliances that operate using electricity or gas.
  Before departing on your trip, you should always ensure that these appliances are in good working order (otherwise, you may find that you cannot cook a meal).
  You should also get these appliances regularly check by a professional to ensure that they comply with safety regulations.
  
• Keep an ear out when travelling If you ever start to notice clunking or grating noises when you take off, slow down or reverse, it is important that you get your caravan's brakes and reversing mechanism to get serviced.
  This needs to be done by a professional, as it is a very touchy repair that you do not want to get wrong.
  

It is recommended that most of these maintenance tasks is completed each time you use your caravan - either before you depart or when you return.
This will ensure that your caravan is always in optimum condition and that everything will be in good working order when you arrive at your location.
It would be the worst beginning to any holiday if you arrived only to find that your appliances or lights are not working.
