Congrats. Did all that, and started with looking at that unit. When the smoke, cleared, we ended up ordering the 'full' CC 36CKTS. That's after buying a new dually, getting a B&W hitch installed, and robbing nine banks in a span of 3 days.
If you are moving up from TT to 5er, you'll need the Progressive Industries 50 amp EMS system. Other than that, the list of optional stuff is a mile long and tailored to tastes.
Congrats and Welcome.
