No issues with the Roo 23SS behind my Expeditions -- nor my Explorer although that truck was right at her limit with that SUV. All my SUVs have had the factory HD Tow option. The max towing capacity for the Expeditions is ~9300 pounds.
Caveat is I'm using the very competent
Equalizer(tm) WDH (not one with chains or a sliding sway control) and a proportional Tekonsha Prodigy brake controller in the '07 and the wonderful built-in Ford controller in the '17.
Ford receivers have a lot of vertical slop and I had to max-out the number of washers in the Equalizer head to tip the ball back enough. I expect this only makes sense only to users of this hitch.
If the dealer sets the hitch it will be wrong. Hurried installation and the trailer will be empty. Takes a couple of hours on a flat surface and good section of road to tune to loaded configuration. This is the same for any WDH.
Same for the trailer brakes which will need adjustment as they wear in.
