Ram towing mileage

I would tend to agree with you, however, I do not know what gear is considered OD in the 8 speed? Is it all of them with an OD ratio, or is it just 8, or does tow haul prevent the torque converter from locking up?

I place mine (5.7/8speed/3.23) in tow haul mode, it definitely holds the shifts longer and provides some engine braking in lower gears, but doing 67-68mph, it is usally turning about 3200rpm. Very rarely does it drop any lower than that, except on downhills where I have had it drop below 2k rpm, but it doesn't stay there long.
