Ok guys I've been doing some research for a replacement truck. Since I'll be going from a gas 5.9 to a diesel I'm sure any of them will feel like a beast compared to my current truck with 268,000+ miles. I had 4.10 gears installed to replace the stock 3.55 because it needed more power with 33 inch tires when towing. I'm wondering how much difference there is between the diesels with 3.42 gears and 3.73 gears. I assume the 3.73 are better suited for towing. Would I notice the difference?
