Yes basically from large fleets down to just one truck. What is interesting tho is that some companies will have on site engineers and as many service companies will admit it is quite competitive market with cost low. If you are a company who operate over 30 trucks ,you can benefit from lower cost's. I don't quite know the North American market and it might be that the managers there prefer the way it is.But with the global market they will be able to match the cost of there operation in Europe to the cost's in North America including down time and then go with the best option that suits there business
