Hi all.

With my slightly modified 3.9 I am getting 12-13 @80. 14+ @65-70.

 

Owned several 15 pass Rams none posted better than 12mpg, I rarely drive faster than 65mph. Add a trailer mileage drops ~8mpg at 65mph.

 

As measured by my BAFX ODB2 scan tool I normally get 18.7mpg at 55/60mph, dropping to 17 - 17.5 mpg at 75/80 mph. I have gotten as high as 19.5mpg on a 20mile trip, and as low as 16.5mpg when towing. Slightly modified 5.2L, Magnaflow 23298 cat, modified ram air, fiberglass front air dam.

 

Mine is the same whether I'm in state or not.

 

Seems like it LOL

I got 15 the other day...I am still holding at 14 mostly.

I guess 3300 RPMS will do that.

 

17 mpg @ 65... I check it every time and it's always 17.
