Well now if we are going to quote fleets of trucks. I believe my brother in law who is a part owner and manager of one of the bigger cement pumping truck buisnesses in the United States and has a large fleet of trucks seems to think that the GM duramax diesels with the Allison transmssion are one of the better trucks on the Market. His company owns a big fleet of them. I know that their is a huge difference between allison light truck and heavy truck transmissions but I do know that the pumper trucks start at about 350,000 each and go up towards a million apiece pretty fast. The ones he uses have allisons. When I was looking at Motor Homes after you got past the 200,000 dollar mark you saw a lot of different engines in them. But a large majority of them had allison transmissions. When you look at the spread of expensive equipment that seems to prefer allison transmissions you kind of get the feeling that they might know how to make transmissions for different applications including light trucks. I pull some heavy loads some times
