The other part is trying to remedy the shortcomings of the popular pumper platforms....
the 13xx and 22xx pumpers are modular but limited in ultimate power output (also not entirely true, but I simplify for the sake of discussion)
the 39x has goodly power, but is limited in its ability to be modded (again, gross oversimplification)
So we have known power plant, and many folks providing after,market support and product.... we should be able to correct a fair amount of the failings of both platforms....
