That's why I ordered my 2015 Laramie with the 4 corner air suspension. Yes, it was $1600 or so, but in the big picture, it was $$ well spent when your buying a truck with a $50K window sticker. And NO, I didn't pay anywhere near that after negotiating and rebates! And YES, it is perhaps the best option on the truck. WELL WORTH the money spent.
