Things I know for sure

Ok guys since some of this known some not so much here goes.
diesel weighs 8.75 gallon so yeah if you suspect a heavy load you can help yourself some but will have to make more stops.
Fuel in the morning gains 1.2 mpg for sure!
Tonneau cover and deck deck plates gain 1 mpg
running naked tandems is gonna hurt mpg.
If no weight loss consider super singles they reduce overall weight about 200 lbs
and are more fuel efficient (check out Prime and some others)

If this will go. Here is cost per mile figures you can use
plug your own in.
1. Tags 1200 and 1200
2.insurance 5.000 year
3. truck payments etc 1200 month $14,400
now the fuzzy ones based on 1,000 miles week
Fuel at 6 mpg always figure this as loaded @ $2.75 gal $2750 wk =$143,000
driver pay DO THIS .35 to .50 mile @ .42 = $42,000
upkeep .25 mile =25,000
living on road $30 to $50 a day for at least 5 days =7800 @$30
Now add this up and divide by 52 then divide that by 7
as so This Total is $239,600 4607.70 wk 658.24 day added week ends to week cpm this one is 4.60 use your own numbers to get a real figure but that's how its done.

 

hey guys this is only an example and was meant to get looked at as I said in post use your own numbers sorry if it wasn't clear. But just yesterday a little north Of Tampa fl saw fuel at $2.65 Gal on I 75 kittypower
