Looking for advice on what normally works on these brinks. Sorry not going to lower it I know that will help.

Here is a link to a technical drawing.
It looks like Chrysler's airdam is already shielding everything except the lower A-Arms.So you might just consider extending the sides down even with the bottom of those.
Looking from the front,you need to establish where the radiator is,with respect to the grille,and where any vertical beams are crossing in front of the air passage.
Cardboard and blue tape would 'show' you what you can get away with as far as temps go.
You're at Cd 0.42,with around 30.937 sq-ft of frontal area,or CdA 12.993-sq-ft drag factor.Chrysler's 2014 RAM 1500 is below Cd 0.36.Some SUVs are 0.34.
