2019 1500 Crew Cab Classic. Problem: my bumper is connected to the OEM hitch which comes with a large hole for the 'ball.' I do NOT want to buy the separate 'adapter' that reduces my towing capacity to 5,000 lbs. I want a one-piece tow hitch with a standard 2" receiver. Do I have to buy a different 'bumper'? If so, what 'year' bumper will work (that DOESN'T need to bolt to the hitch)?
