hey john , the truck is a mitsubishi fuso fh. it has a 6 cyl diesel with an allison automatic .. i went on a big serach for this truck cause the 4 cyl models dont have such a great transmission ... they say allison is the best you can get... its a 15 ft fiberglass box..... i looked into all the trucks you mentioned but i wanted a truck that would be easy to put someone in and drive.. besides this thing rides better than my car.. the turning is incredible .. as far as mpg's i never estimated that but its better on fuel than my friends ford econoline van that has a v8.. i truely love this truck and would buy nothing but cab overs..... it has a gvw of 19,500 .....i took everything in account when selecting a truck ...i wanted to be able to put multiple drivers if needed and i wanted to be able to manuver around yards and traffic.. to me this is the best choice you can make ............... hey ron im sorry i suck with the computer .. its a whole process for me to dl pictures.. i will try my best to add a signature.. thanks
