Since I can't afford 2 trucks, and I can't drive a car for any length of time due to arthritis and back/leg issues, I need a daily driver that can also tow. Right now it has been an F150, which does OK, gets 7-9 with my travel trailer, and 17-18 on the highway. My last one was a 14 RWD and got about the same towing, with 3.15 gears at that, and 20+ during the summer and 18+ during the winter.
I drive 120 miles a day on rural state highways, averaging 51 MPH over the past 140K miles, set the cruise at 63 and sit back and drive.
My current 16 has bee nothing but problems since hour 1. I plan to replace it and would like to go to a Superduty, and because of all the miles I drive was looking at the diesel. I had a 99 Dually with the 7.3 and got a consistent 18+ MPG in it, and have seen that the 6.7 can get that as well, if not better since I stick to 60ish MPH.
Now IF the 6.2 could do 18, I would easily consider it instead, but 15 MPG or less is out of the question. Just in a couple road tests of a 17 6.7 I was seeing over 20 MPG on the lie-o-meter, ut haven't even seen a gasser around to compare.
Anyone driving daily on 55 MPH highways for 60 miles one way? What are you seeing?
Also what is the average payload in the F250 with gas? The 6.7 leaves very little payload, so an F350 is a must for Diesel when towing anything over 8K pounds.
At 60-65 MPG on the highway in fairly heavy traffic, I'm seeing just over 15 on the highway, with a bit of local driving mixed in. My truck has 4.30 gears and is not broken in yet.
Payload on my heavily optioned F-250 Lariat Crew 4x4 gas is 2980 lbs.
