I ordered factorybrake controller. As far as the other Mopar tow items. I thought the 5th Wheel and Ball options were Mopar Accessories to be installed at the dealership not factory installed items. I might be wrong on this though. Ram brochures both online and at some dealerships are available now and list the options. I do not remember ball or 5th wheel being available on build my Ram site.

 

I also ordered the trailer brake control. Auto w/4.10's
