Hey folks,

I have been reading and absorbing all of this.

I have a 1999 Dodge Ram with the 5.9 liter V8 in it.... so any little bit helps.

Welcome! You should enter your truck into the garage where you can keep up with your per tank mpg and your average mpg. There seems to be a lot of useful information on this site. Good luck!

Welcome!

Do you have a cap on your bed?

If not, do you leave the tailgate down?

No Cap
 

I don't have a cap or leave the gate down.

From what I have read, that is not conclusive.
