Road master Base Plates for Dodge 1500 will fit multiple years, mine was a 2013, but I am told by etrailer.com personnel that this base plate will fit 2012 through current year. I will try and post pictures to show how it fit on my dodge.
It will be 300.00 shipped to your door, they sell for 450.00 at etrailer.
Although I did install them on my dodge, they were never used. As before we used them, I traded the dodge for a Jeep, 2019 unlimited. I have all the parts, screws, bolts and instructions, although the instruction video available at etrailer is much better than the instruction. Pretty easy install, this old 77 3/4 year old Marine did it in a couple of hours.
These are the type that are quick release and requires no bar across the front. They are made for a roadmaster tow bar, but there are adapters available to allow them to be used with blue ox or others.
Sorry two of them came out upside down, just turn the computer on its head to view
Thanks for looking
