You should always keep your caravan in tip top condition. Regular servicing and maintenance will pay off in the long run, giving you greater reliability and peace of mind. Be careful however, there are safety and legal issues to bare in mind. Every vehicle or trailer is required by law to be in a condition where it can not, by normal operation, cause danger to anyone. Some items can be checked yourself, lights and tyres for example, but the braking system, gas and electrical systems and habitation area are best left to the experts.
