This is the other half of Don and Patti. I would weigh your options for towing your Bronco. Number 1 consideration is if can be flat towed (all 4 wheels on the ground). Number 2 is the weight, Ford lists curb weight between 4,300 to 4,900 lbs. That is certainly within the towing capacity of the hitch, but will require VERY solid attachment to the tow bar and the Bronco. I would not recommend trying to modify the built in tow hooks or plates. I would get a tow kit specifically designed for the Bronco from a reputable company like Roadmaster or Blue Ox. Number 3, mandatory safety item, get a supplement brakeinv system added to the Bronco so its brakes are activated when the RV brakes are applied. And number 4, I would seriously consider having a 5Star modification to the PC's computer done. I realize the newer models E-450 cutaways have a V8 engine rather than a V10 like my 2015 2551 has, but the 5 Star update made mine FAR smoother in its shift points and allowed better speeds up mountain passes (we have a few in Colorado). No mstter what you do, expect a significant drop in MPG while towing a Bronco.
Last point, do not attempt to backup while the Bronco is being flat towed. It cannot be done
