Hauling heavy loads wear and tear

[Lonestar10]

lets put it this way...my dads own thoughts... he would never go back to RGN again... pays more yes...BUT you bounce ALOT more often then not he had 300-500mile bounces to get loads. he is currently making more PROFIT running flatbed with the company were leased onto then he was running under his own authority doing RGN. his revenue was larger but after bounce fuel/time/permits it was less than now. his t-600 averages 5.5-6mpg with stock 500HP cummins tune cm870 running mainly 65-70 and some 75 when in a hurry. his truck is the reason im so unimpressed with my bignose "prostar" having to baby the crap out of it just to get 5MPG with a demanded/6 new injectors/all new fuel actuators/13sp/500HP Tune cm871. so far ive put somewhere around 8,000 in new parts to go from 4.8ish to 5ish even running 25-30k loads at 65-67. dont get me wrong with this week averaging 2.85 per mile im making some good money but i could still sip a bit less fuel.

only thing left for me todo is put on a new head since when they overhauled it before i bought it they didnt replace.
