Manufacturers and Customer service

When will all the caravan manufacturers Take full responsibility for their product and stop hiding behind their Dealers. They all hide behind the fact that your contract is with the dealer you purchased from. They refuse to deal direct with you and expect you to cover all the costs in time and fuel to get your faulty van to your dealer. Other Dealers who may be closer to you will not touch your problem with a barge pole as the manufacturers  will almost always make it very difficult for the dealer to get his money. Why oh why can they not operate like the car industry???
