I have noticed my dome light is also dimmer in the mornings. I'll bet it is the Battery. Yes we are in the same area for winter weather. When it gets down to 24 degrees, we are FREEZING!!!
I drive through Brandon on the way to Tuscaloosa quite a bit. My daughter is a freshman at the Univerity of Alabama. The McDonalds across from Gray-Daniels Ford is our first stopping point for bathroom breaks. It is the halfway point from West Monroe to Tuscaloosa.

The 300sdl loves that 300 mile trip. I blow out a lot of city driving junk on that trip. It is a true Interstate cruiser.
