[QUOTE="xjmarc, post: 760021, member: 2494"] I love the 4.10s in my 3rd gen 6.7 Cummins. While it doesn't get the mileage my 12 valve with 3.55s did, not towing of course, it does me just fine. On that note when I decided I needed a tow rig I got a Chevy 1500 Z71 that averaged 4mpg towing my jeep, slightly better down hill. I replaced it with a 97 12Valve Dodge 2wd and got around 18 towing and my best unloaded was 23mpg but the 3.55s brought the suck taking off and crossing mountains. Briefly had an 04 2500 Cummins 4wd, no clue on gears but it got about 16 towing and was slightly better climbing. My current 07.5 2500 Cummins was getting about that till I deleted and tuned it. Now it gets around 18 towing and less unloaded because I drive it like a hot rod. All 4 were autos so with a manual I might be able to get a bit more but I have a fused ankle so manuals suck for me. Also my wife said I wasn't allowed to get a gas truck as long as I planned on towing anything. [/QUOTE]
