FWIW, I'm pulling a 17' Winnebago that weighs about 4500 lbs loaded on 3.42s with a 6L80 and 5.3. With my 275/65-18s (32.1" diameter), the effective gear ratio is 3.40. I'm also looking at some Cooper Rugged Trek tires and they're 32.6", which bites into the gearing even more. So I'm not crazy about it and am thinking about 3.73s as it's still a daily driver. 4.10s might be a bit much to my way of thinking but I'm open to thoughts.
Just got back from a 3000 mile trip up and down the east coast and Allegheny Mountains and spent well over 50% of the time in 3rd and 4th, twisting the engine between 3500 and 5000. Guess I'm glad it's a Corvette block at heart...
