I took a look at the online version of the owner's manual for your 2018 Buick Envision AWD and found that it can be flat towed behind an RV with all 4 wheels on the ground. I do recommend verifying this information in your copy of the manual as well as reviewing the specific steps you will need to take before pulling the vehicle. |

This kit will allow you to wire your Buick so it accepts the needed signal lights from the RV while towing. It includes a 6-Way that you will mount to the front of the vehicle and enough coiled wiring to go from there to the 7-Way on the RV. |

In addition to base plates and a tow bar, you'll also need safety cables (not vehicle specific), tow bar wiring, supplemental braking and potentially a high/low adapter to allow you to tow level. For tow bar wiring I recommend using the Roadmaster 7-wire to 6 wire Diode Kit # RM-15267, which will allow you to protect the towed vehicle from electrical feedback from the RV that might damage your Buick Envision. |

Most likely you will also need a high low adapter so that the tow bar will be level when you are flat towing. I attached a link to a page that has all of the ones we carry. | When you explain about the flat towing of a Buick...

Even if it is not, a supplemental braking system is a very good idea because it makes flat towing a vehicle such as your 2017 Buick Envision much safer because it will allow your RV to stop at a quicker pace. A supplemental system is also going to put much less strain on the braking system and chassis of your RV and Buick which is much better for both vehicles. |

Here are the parts you will need to flat tow your 2019 Buick Envision: Tow Bar and Safety Chains - Roadmaster Falcon 2 Tow Bar item # RM-520 and item # RM-643 Base Plate Kit - Roadmaster Direct-Connect Base Plate Kit - Removable Arms item # RM-523196-5 Wiring Harness - Roadmaster Diode 7-Wire to 6-Wire Flexo-Coil Wiring Kit item # RM-15267 Supplemental Braking System - SMI Stay-IN-Play DUO Supplemental Braking System item # SM99251 or item # SM99243 if your motorhome has air brakes High Low Adapter - The tow bar needs to be within 3" of level. If you measure the height of the inside top of the hitch receiver tube on your RV, and the height difference is more than 3 inches above/below the base plate tab height, you'll need a high/low adapter. |
