High fuel mileage specs?

I will tell ya pulling a flatbed you really wont see to much of a difference between a rooster cruiser and a vacum cleaner....

Also the best truck today is the one with NO PAYMENTS, if your 359 is paid for and gets 5-6mpg comparing to a 387 that you will owe 50+K on and get 6-7mpg (yeah right not on ULSD) i really dont see the point.

 

Friend of mine bought International Prostar midroof with ISX 500HP ,13 speed Eaton fuller and 3.73 rears.He's haul stepdeck coast to coast,so far his average MPG is 5.8 and hope to improve to 6.0 at least for summer time.BTW cab inside extremely quiet even compare to my VN670.IMHO this Prostar is a best choice for hauling skateboards.

 

525hp + motor not newer than 03, unless you take your cat off the bridge, 3.55 or 3.70 rears and an 18 spd. Mid roof bunk should do just fine unless you are going to be 13'6 all the time. Also set the computer to not let you go faster than about 62 mph

 

i got a fresh C-15 475hp 10sp 3:55 rears i run 1475 rpms at 70 mph and i'm gettin 6.8 mpg

 

Easymoney, I cant really speak from experience of my own, but I have talked to several O/O's, various co.'s, driving 379's pulling flatbeds. Each one has said they were getting 6-7.5mpg. They did it by letting off of the right peddle. Stayed pretty much at 60, occ. 65. According to them it didn't cost them much in miles and saved a ton of stress. Also talked to a guy on the radio who had it figured out that for every mile per hour he went below 65 he put $33 a week in his pocket. His words, no proof.

 

I run a 379 exhd. When I pull my flatbed I run wood beams loaded 24 inchs off the cab. I run these beams with a couple of other trucks same route everyday and pull a 1/4 of a mile to the gallon less then their freightliner centurys. I am spec'd with a 430/470 detroit, 485 program overrode 10%, a 13 speed, and 3.90s on low pro 24.5's. I have never seen much of a difference in fuel mileage pulling my flatbed no matter what I haul. When I hook to my reefer tho then the fuel mileage drops about a mile to the gallon.

 

You don't use all 18 most the time but the time when you need them and not have them is when you'll kick yourself in the butt. When you have to stop on a big hill with 80k on and you can't get your ten speed to grab more then 3rd gear without coming to a stop it will be a long trip to the top. Plus the 18 has a super low reverse gear which I like. ANd it has a higher torque rating then the rest. at least it did back when I was buying trucks.
Maverick sells allot of trucks, if you like them go look at what they have
