I'm not sure if anyone has discussed this particular scenario, I've poured through a number of different regear posts but I haven't found anything that really answers my question. I have a '14 Silverado DC z71 I purchased in 2015 used. I got a great deal on it, only 19,000miles and looked like it had never been driven. The dealer I got it from I had known years ago, his wife used to teach me horseback riding lessons when I was a kid. He told me the truck was 3.42 as well as another guy Arbizo the dealership. It took me too long to realize it's actually 3.08 so I'm basically stuck with it. I love the truck and it tows my ~6000lb horse trailer fine but I'm looking to Regear. I just don't love how it handles some of the hills and back roads I drive with the trailer. It always makes t but I feel like it's working too hard and I want it to last a while without needing a new tranny etc. I don't plan to lift it or add bigger tires or anything like that. All I'm looking for is improved towing (I know changing my gears won't Change my tow rating I'm not looking to tow anymore I'm just looking to improve towing performance for what I tow now within the trucks capabilities). My question is should I upgrade to 3.42 or if I'm going through the trouble am I better off just going to 3.73? How will 3.73 effect my gas mileage vs 3.08? I know it's a truck and I'm not looking for crazy mileage but don't want to be going to the gas station every other day since it's my daily driver also.
