gear ratio.
hey all, I'm looking at purchasing a new tow vechicle. I believe I'm going diesel, but wondering what people think a good gear ratio would be for towing 9,000lbs. I see most 3/4 ford have 3:55. I was ...

If you do go diesel, gear ratio is less of an issue; yes, a numerically higher ratio provides more wheel torque, but the primary reason folks love to tow with diesels is they produce their torque at much lower RPM than gasoline engines...so, a diesel doesn't "need" low gears to get into the optimal powerband as a gas motor may.
Also, as powderman said, newer 5-and-6 speed automatics make rear end gearing less of a factor than with the older 4-speeds. Likewise the crazy amount of power these engines produce; with 800+ ft/lb of torque, lower gears just simply aren't as necessary as before.
