How much weight are you pulling?
I had a GCW of 17,800lbs a couple weeks ago, and am pleased with my 3.73.

What transmission? 6 speed manual, then go 4.10.
48RE automatic? Then dont go any farther than 3.73

And I'd suggest exactly the opposite Don.

The 48RE has a 0.69:1 4th gear ratio so would be OK with a 4.10, the G56 6 speed 6th gear was 0.79:1 in that year, and the NV5600 6th gear was 0.73:1, so they would rev very high at highway speeds with a 4.10 and would be better with a 3.73 IMO.

You don't have a 3.54 - it was not available on third gens. Check the sticker in your glove box. If it has the 4.10 option it will show on it but if it has the standard 3.73, it wont show anything.
