my RAM with the Green diesel tune gets 22 when i push it around town, 23 when i'm in a better mood. daily 12 mile commute, several weekend hauling jobs and 3-4 hour drives, plus the occasional airport sprint... when i haul the mail to the ATL airport (2h 17 min away from my house and make it in 2h, i get 25.7 when i do the speed limit, i get 31.5 (!) - did that to Pittsburgh and back once 6x12 with a bike in it will get 18 MPG at 10 over. tow toy hauler at speed limit will get 12-14, depending on hills and patience. tow toy hauler in a hurry: 9MPG . but that's doing 80-85 for the issues: at 55k miles now, bought with 11k. towed the heck out of it. i have a spare high pressure pump on order, that i'm planning on disassembling and having it DLC coated. there is a cam gear issue, where i'm still debating on a solution on... but that will get fixed / bulletproofed too. i love that thing.
