Hey Steve! We don't have a kit but I can put the parts together for you. Do you already have the tow bar or are you looking for an NSA one through us? We have tow bars like the Roadmaster Falcon 2 # RM-520 but NSA isn't a brand we carry. You will also need a base plate kit, wiring, and a supplemental brake system if you don't have the NSA one already. I recommend the following:

-Roadmaster Direct-Connect Base Plate Kit - Removable Arms # 1541-5

-Roadmaster 4-Diode Universal Wiring Kit for Towed Vehicles # RM-15267

-Curt RVi Series Shadow 2 Flat Tow Brake System # RVI94FR (includes charge line)

You may also need a high-low adapter like the etrailer High-Low Adjustable Adapter for Tow Bars # e52ZV to keep your setup level. I attached an article further down on this page which explains how to measure for an adapter.

Any big trips planned once you get your Element set up for towing?

I do have the NSA tow bar, it has it's own braking system and set up for blue ox backing plate. I also have a 7 to 4 pin adapter to connect MH and toad. Would the wiring for tow bar lights and the toad trailer lights (i plan on trailer hitch) be separate installs? I'm planning a trip to Maine and the Bay of Fundy.

@SteveK for Blue Ox you can use the # BX2232. If you're wanting to connect to a 4-way on the vehicle side you can use the # RM-154 instead. Tow bar wiring and vehicle wiring are really all the same thing. The installation happens on the vehicle and then you will connect that wiring to your motorhome using the 7-way to 4-way adapter you have.
