The side bars safely clear the RamBoxes when they are open, while keeping any cargo such as a Rooftop Tent as low as we can to maintain a healthy center of gravity and to keep cargo accessible. The front of the rack has a CNC formed contour to avoid blocking the third brake light (CHMSL), while tying the two sides together. This allows for full-height items to be loaded into the truck such as dirt bikes, and adds the utility that when a tall and bulky item is loaded into the bed, it can be surrounded by the crossbars to add stability to the item. The unique design of the rack and load-bearing crossbars allows the rack to be broken down for shipping or storage, and for the crossbars to be moved to any location along the length of the rack, or completely removed. This rack is everything you want it to be when you need a rack, and is completely out of the way when you need open bed space. The flat floor in the new crew cabs (1500's) definitely offers more storage under the seats then the current cab, so that should probably fix the problem.This rack has been designed specifically to provide a well thought out bed rack for the RamBox equipped Ram chassis that is both versatile and accommodating of the great features that the RamBoxes and Cargo Management give us. A toolbox or ram boxes in the crew cab would fix this, but for me, both are not an option as I have a sled deck on my box in the winter and both wouldn't be accessable with it on. The Mega Cab is unreal for storage under, and behind the seats, at least 4-5x as much room as I have. I don't even have the factory sub, which would eat up 2/3 of that. I can barely put a hitch and a small tool kit under the seat and it's full.

The Crew Cab is big enough to be plenty comfortable sitting in the rear seats IMO, but it sucks for 'wet/dirty' storage. We go out in some remote spots snowmobiling and camping so we keep a bunch of tools, tow straps, tie downs, emergency supplies, etc in our trucks (plus the all the regular 'truck' stuff). My dad has a '07 Mega and I have a '11 Crew Cab, the ONLY reason I'd consider the Mega Cab is all the extra storage options in the Mega Cab.
