[trooper Tdiesel]

guessing replacing the auto is not likely to happen.

sounds like it may be like are area, where its up to the person delivering the mail to use there personal auto to cover the long miles. and the USPS pays per box delivered to or per mile or something else.....

being major stop and go, shorter narrow tires with high pressers will help with the non stop powering up to speed, stopping and then repeating on and on and.........

every one in my area that delivers mail goes thru sevral sets of the life time brake pads a year.......
so yea its really worst case on mpg.
driving down hill as much as possible will help as well, but i do under stand in most all cases there's homes on bolth sides of the road....
so doing the down hill first and the up hill after fluids have heated up will help, but not very much....

shutting off the A\C will help, probably about a 1/2ish mpg or so.




spent a term in the city with my trooper and went to a little 225/75/15 passenger car tire, helped with driving at speeds around 20 to 40.

but with the 4.55 diffs she did not like going over 55 mph with the smaller tires, rpms where extra high and i had around a 1mpg loss at 55, the higher rpms with the diesel was more the big issue....
i just stuck to 45mph and under roads the hole time.
