Congrats on your new rig! Our 2016 262RGX had a horrible couch so we replaced it with a Lazyboy love seat and chair which made the rig so much more comfortable. One thing I don't care about is no drawers in the bedroom, but we deal with it. Besides a couple of minor things, we love the layout and my wife really loves the rear kitchen.
I did have a 2011 1500 with Ram box and can see why there would be clearance issues with that bed because the bed sides are so thick. Although all I towed with that was a ATV trailer. My current 07 CTD short bed has no clearance problems whatsoever with an Anderson hitch.
One thing I hope to do soon is upgrade the 15" wheels and D rated tires on the Wildcat to 16's and at least E rated tires. But will probably go with G rated 14 ply Sailun's. Here in Nevada we go on little used highways in the middle of nowhere and the last thing I want is a blowout.
