The Ram is a daily driver with mostly Interstate and Highway driving very little stop and go city driving and short trips are avoided as much as possible...
I live in Oklahoma so cold winters are not that bad but there are many days of 0*F weather... The Ram will be in the garage at night... Only at work will it be exposed to long periods of winter weather...
The 2 oils I am drawn back to are the 10W-30 Pennzoil Platinum and Ultra Platinum...
These are the Pure Plus Version... I did not post the Ultra Versions..

My question is as stated above-->Is the 10W-30 the better choice then the 5W-30 for an owner who is using a 30Wt oil?
10W-30 and 5W-30 are the same viscosity at operating temperature.
With this being said, 5W-20 is recommended for that engine for all temps according to Chrysler.
