If you're concerned about your paint under the molded Dodge guards,
put a layer of 3M clear protector on first.
I ran my Ram last Winter with the "dealer installed" Mopar molded guards,
I removed them for the Summer drag race season to find dirt/sand that got trapped between the guard and the fenders rubbed the paint off
Had a fight with the dealer about re-painting the lower fenders, still not resolved.
I prefer the non-flap look, but definitely need the extra protection in the Winter here, my rocker panels take a beating!
