Fashion statement
I have the WAAGs with dually kickouts on my 3500 4x4 and am very pleased with them. (link in my sigfile below). One thing you should be aware of is, that before installing any wheel-to-wheel sidebar, you should very carefully consider, whether or not you are going to haul a slide-in truck camper, because if you have a preference for the Torqlift camper tie-downs for instance, then wheel-to-wheel bars will use a (common) location point thus preventing you from using the two together; the way around it is to consider the use of the Happijacs camper tiedowns mounting system, but there are cons as well as pros to be taken into consideration.
Good luck!
