MPG

It is amazing. I saw a guy with an APU ideling all afternoon and he had a newer truck and the same APU I have so asked him what was wrong with it. "Nothing - the air vents blow right at me so I use the air from the truck to stay cool"

It was in the 50's and dropped to low 30's that night. Would have been cheaper for him to get a hotel room at current fuel prices.

 

In 2007 I bought brand new VN780 with Volvo engine. I drowe it for 2.5 months and forced Volvo to take it back with the full 125 K refund + 2 K unnecessary expences. The bad fuel milage was only one on the long list of bad things about that LEMON truck.
I would never even consider buying any Volvo again...probably not even in Europe!

My 12 years old Detroit after totaling 175176 neatly recorded empty + loaded miles and included all winter/summer (2+2) idling during last 24 months gave me 6.8 mpg. My average speed is, I guess around 61 mph...ranging from 54-78 depending on the appt schedules on each load.
I never drive faster in order to be sitting at the truckstop longer.

My sincere advice is try to get rid of Volvos asap and get some good old Detroits.

 

P.S. If you raised your average mpg from 5.0 to let's say 6.5, at 100.000 m/y and $4.00/gal, your revenue would increse $18,500.00. Definitely worth consideration I would say.

 

I am going to guess your drivers are not speed limited, and they are idling their trucks every night

 

I was in Ganado, TX on Wednesday and there were 4 trucks all idling while it was 72* outside. Once it dropped to 58* that night, almost the whole parking lot was idling......at $4 a gallon, that is just plain insanity. I curled up inside my sleeping bag and was nice and warm and saved $50 on the night
