Flat Tow 2019 Buick Envision Set Up


I need help choosing a flat towing setup. RV has 2 receiver, but tow car has nothing. There are so many options baseplate, tow bar, electrical, braking, etc.... Do you have folks who can give me details on both BlueOx and Roadmaster complete systems?

You asked about Blue Ox and Roadmaster complete systems but set ups to flat tow a vehicle are an a-la-carte situation where the user picks the pieces that they prefer based on features and value. In my recommendation below I have parts from several companies. Personally, where value is equal, I prefer to use one brand mainly. In this case, Roadmaster, as they carry many of the pieces we need and I can be assured that they will work together well.

To flat tow your 2019 Buick Envision behind your vehicle with a two inch receiver hitch you will need
the Roadmaster # RM-523196-5 direct-connect base plate kit that has been designed specifically for your Buick.

Coupled to that will be your Roadmaster # RM-522 All Terrain – Non Binding tow bar which will allow you to connect your towed vehicle on uneven surfaces. You could otherwise select the Roadmaster # RM-520 standard tow bar. Both bars will connect to your tow vehicles 2” receiver and are rate for 6000 pounds which is more than enough for your Buick. You must add to your tow bar some safety cables. A good choice is the Roadmaster # RM-643 cables that are 68” long and coiled to keep off the ground.

If, when on level ground, the connection between your coach and tow vehicle is high or low by three inches or more you will additionally need a hitch high/low adapter like the Blue Ox # BX88130 with 6” high or low offset. I have attached an article describing high/low adapters and how to determine if you need one and what offset measurement to purchase.

Next you will need a vehicle tow bar wiring kit. I recommend the Roadmaster # RM-152-1676-7 this complete kit includes everything you need to connect your RV's tail, brake, and turn signal lights to your towed car. Diodes prevent feedback and wire your car to operate as a combined system.

Your towed vehicle you will need a supplemental braking system which activates the towed vehicles brakes in concert with the coach. If you coach has hydraulic brakes I would use the Brake Buddy # HM39494 which is the classic value-priced model. The # HM39524 model adds a wireless display in your coach to show brake status and to change profiles if desired.

If your coach has air brakes you will instead need the Demco # SM99243 Air Force One supplemental braking system.

Since you are using a supplemental braking system you will additionally need a brake light relay # RM-88400 added to your setup.

This is a lot of parts and it may seem daunting, but I assure you that lots of our customers install these entire systems themselves all the time. Each of these products come with instructions and some have install videos. I will attach these where available.
