Thanks guys. I am a little bummed that the truck only came with 3.42s. I think 3.73s would keep me in 6th more.
What did you want? To tow the world in double overdrive?
Yeah the new trucks like yours might do it with deep rear gears, but I would t be bummed. I would t have even asked the question.
I tow or haul in 6th, but my 6th is like your 5th and you don't know much about trucks if you're asking this question, so yes 5th is the proper and preferable gear for what you're doing. Unless you're doing like 90+ with the 5ver behind you, in which case 6th should be well enough into the powerband to run it as well!
To not be so sarcastic, you won't experience any better mileage with running a few hundred rpms less in high gear as opposed to 5th. And it won't hurt the engine either. These motors will pull hard down low, but lugging them and high egts is not what you're after.
You got the best rig out there IMO. When pulling heavy on the flats, pick whatever gear keeps you over about 1800rpms. Going up hill, keep er at 2k rpms plus.
