2014 Ram 3500 vs Ike Gauntlet

GM has stuck with 3.73's since the inception of the Duramax in 01 in the pickups. My 5500 has 5.19's. I have to think they could run more trailer weight if they offered a 4.10 or so option. It does not appear at least right now that they will. The combination has proven very competitive over the years. It may not be ideal in a run up Ike however. I would be curious if they spec the truck or let the OEM spec the truck for the task. GM does not have any options, but Ford and Ram certainly could provide a truck geared specific for that task.
