Howdy all, i am seriously considering stretching either a western star 5964 or an International 9400 in the next few weeks, both the trucks I am looking at have around 350k on them one a 3406 cat and the other a N14 cummings, both eaton super 10's.. Anyhow my question is for anyone who has had this done to a used big rig.. Have u had any problems with the truck, motor, tranny or chassis due to the stretch? Does it drive straight? What kind of fuel mileage are u getting? And should I expect any engine problems due to the 350k miles on it? My reason for these trucks of choice is the shorter angled front-end, the setback front axle and the side exhaust.. So I have done some research.. I currently have an FL70 with almost 200k on it and I am just ready to upgrade.. Any info or advice would be great.. Thanks, Andy
