no industrial is 700hp marine is 900 inline 12.75 marine is 750hp as much i know marine engines are pde not only cgi but also block is much thinner on unnecessary places
yes in late 2007 i hope that they use opportunity to realize how to build it better on experience of other manufactures anyway since here fuel is very bad quality there was some problems with them on early trucks in meantime fuel quality is bit improved now pretty lot of xpi trucks running here including dc9 and dc13 but still not dc16
and it is better if you dont know what is all inside dont look too good there is stove half of house kitchen , improvised bathroom...... not best looking inside truck have a LPG also i think 670hp or 680
