A SRW 3500 with 3:43 axles doesn't have any issue whatsoever tugging 15K along America's highways. Just maybe, that is why RAM's engineers made the 3:43s standard on a SRW.
The 3.42s on all SRW 2500s and 3500s are a result of government fleet fuel economy mandates.

I didn't think 3/4-1 tons fell under EPA MPG guidelines. Why do 2500/3500 6.4s come with 3.73s? They could put 3.42s as standard on them and even better fuel economy.
