been running my 85 brig with a 238n 10 speed fuller and the place that I am signed in to to haul demo trailers run me with around 60-65k of weight. it is getting 4-5 mpg local the 'big' boys are only getting 5-5.5 hauling the same ten ton , as that is all that will fit into the trailers . short 28 ft trailers they are at close to 80k as the tandem tractors are much heavier . My light wt is 12580 full fuel. It doesn't matter how many hp it's in town with 35-45 mph speed limits we all get to the transfer station at the same time Is there a way to get more milage from 238 hp? the big boys have 425 cats and dd16 s set at 600 and get about the same milage. but are much faster on the freeway. any ideas?
