Just trying to compare and decide between these two packages for a Big Horn and figure out if the Night Edition is worth the extra $1500 or so. They appear to both have painted bumpers, but the Night Edition has a black grill and blacked out logos, etc. in addition to 20" wheels., right? Am I missing anything else significant? Is the grill on the Sport Package chrome or painted? How does these painted bumpers hold up to rock chips, etc.?
