I agree with you Barry that personal education is very important and not good skilled personal is in the most cases the reason for accidents. I think as truck supplier it is important that you bring a product to the market that is covered by one declaration for the whole truck including Ex conversion. Mostly the customer buys a truck from one company including the EX rebuilding. If there is an accident caused by the truck the customer should only communicate with truck supplier and what happens between truck supplier and rebuilding company is not the customers problem. He needs to be covered by the liability assurance of the truck company and not to worry about all other aspects.
