DO NOT TOW MORE THAN THE RATED CAPACITY OF THE CAR.
It is dangerous, It can cause premature wear to the car and mechanical systems. Improper balance, no brake controllers, and improper sway control can result in rapid and unexpected disaster, resulting in major damage, and potential injury of people.
Do not do what I'm doing.
And now that I've said that; I'm going to ignore it
2019 Buick Envision, Essence. 2.4L 4cyl N/A Front-Wheel-Drive. (No Turbo)
We all know the Envision has a rated towing capacity of 1,500lbs.
Trailer; 2023 Rove Lite. Expected weight when loaded is 2,100 lbs
So, Yeah. Get your hate out now. "Buy a truck", "Get an Enclave"...
This is me recognizing and accepting the mechanical risks, and mitigating risk of accident via installation of active (differential braking) stability and sway tech + brake controllers.
First and foremost: so I can enjoy the camper, and car to it's fullest, and secondly to push this car and its architecture to the limit - for future people can see what I do, and elect not to do it unless they understand the caution needed.
Results of driving 5 hours on the freeway on reasonably flat land.
Opinion: "Tows ok. It's no truck. Sway controller is definitely a requirement, as my electronic sway preventer would turn on when I'm passed by semi-trucks. The Curt Echo brake controller (inertial, wireless) coupled with the Envisions oversized brakes does a great job bringing the speed down from highway to exit ramp speed. Tow mirrors are needed"
