To flat tow your 2020 Buick Envision behind your Tiffin motor coach you will a few parts starting with a vehicle specific base plate kit. For your Envision I would choose the Roadmaster # RM-523196-5 Direct-Connect Base Plate Kit which features simple twist and lock attachment, and it hidden very well when not being towed.
Next add a tow bar. An excellent choice here is the Roadmaster # RM-522 All Terrain Non-Binding tow bar. A non-binding tow bar will let you easily disconnect your tow bar even if your coach and towed vehicle is not on level ground or at a difficult angle. The tow bar is the one point in flat towing that gets the most stress and wear. You don't want to go cheap or used for this most important part. You can save a few dollars by using the Roadmaster # RM-520 standard tow bar if you don't mind the extra hassle when on uneven ground. I have attached an article comparing the two styles.
You will also need safety cables to keep the towed vehicle connected to your coach in case of a tow bar failure. I would recommend the Roadmaster # RM-645 which are 64” long and rated for 8000 pounds. I like that the connectors are made so they can not bounce off the cable hooks. I also prefer the straight cables compared to coiled – it just looks cleaner when they are all tucked away. If you find that your clevis hooks will not fit through the ears on the back of your coach you will need to add Roadmaster # RM-910022 cable connectors rated for 6000 pounds.
Next you will need a tow bar wiring kit. I recommend the Roadmaster RM-152-98146-7 Universal wiring kit which 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. Includes a 7-way to 6-way straight adapter cord. When you do finally get ready to plug your electrical cables in I would put a little Edelmann # 11755 dielectric grease on those connections. The dielectric grease will keep help keep moisture and corrosion out of your connections.
Your Envision requires two fuses to be pulled when flat towed. You can either manually pull them when towing and return them afterwards or you can use a Fuse Bypass Kits like the Roadmaster # RM76512
You may also need the Roadmaster # M-751000 Brake Light Switch Kit. To determine if you need this place the ignition of the towed vehicle in the tow position and see if it's brake lights work. If they don't work, you will need this kit.
Your Envision weighs in about 4000 pounds so you will need a supplemental braking system installed in it. This will improve braking and handling, and extend the life of your coaches braking system. Additionally, most states require supplemental braking if your towed vehicle is over 3000 pounds. If your coach has traditional hydraulic brakes then I recommend the Brake Buddy # HM39524 portable system that has proportional braking and has a wireless display for your cab so you can see your braking system status or change profiles from your driver's seat.
If your coach has air brakes, then instead of the Brake Buddy system, you will need the Demco # DM26VR supplemental braking system for air brakes.
