Question:
I’m looking to buy a BlueOx hitch and setup. We are buying a Tiffin Allegra Bus 45OPP and I want to flat tow a 2019 Ram 3500 4x4 dally. Can you tell me the pats I need to have installed in the place of my 4x4 hitches? And then what part is the full hitch that connects to the Coach.

Hi David; to flat tow your 2019 Ram 3500 you need a tow bar, base plate kit, safety cables, wiring, and a supplemental brake system. I'm assuming you mean you want to use a Blue Ox base plate and tow bar for your setup. I recommend the following:
-Blue Ox Base Plate Kit - Removable Arms # BLU86CR
-Blue Ox Avail Non-Binding Tow Bar # BX7420 (includes safety cables)
-Roadmaster 4-Diode Universal Wiring Kit for Towed Vehicles # RM-15267
-Demco Air Force One Flat Tow Brake System for RVs w/ Air Brakes # SM99243
It looks like your Tiffin Allegra Bus has air brakes but if you actually have hydraulic brakes use the Demco Stay-IN-Play Duo # SM99251 instead of the Air Force One. I'm assuming you already have a hitch and 7-way on your motorhome. If you don't let me know. Also, you may need a high-low adapter to keep everything level. I attached a help article below which explains how to measure and choose the correct adapter.
