I tell ya...I love this fold flat floor option that came with my quad cab. For the longest time I was aiming to get a crew cab because I wanted the space back there for my kids, but couldn't find hardly any Sport crews in my area without driving a couple hundred miles.
For those who have kids in booster seat, my salesman (who also has toddlers and a Ram Quad Cab) lifted up the seat and pulled out the fold flat floor. Confused why he was doing this, he said "watch...let me show you something." Placed the kids high back booster seats once we put the seat back down, and then watched them climb up this massive truck. Since my Sport came with the step bars I was pleasantly surprised to watch my toddler anxiously climb into daddy's new truck not only by themselves, but were able to climb in their seat with ease. The fold flat floor not only provided a mini platform for them to step up and sit in there booster seat, but their feet weren't dangling while sitting in the seat. It was then that I quickly got past not getting the crew cab. Kudos to the Ram Truck designers...very cool.
Anyone thinking about doing this mod for their crew cab, another bonus if you have small kids.
