To tow a front-wheel-drive car safely, you typically need a special carrier that lifts all four wheels off the ground, which significantly impacts the towing capacity needed.
You must check your RV's owner's manual to confirm its towing capacity before attempting to tow anything. Even if your RV's capacity seems high enough, the Cobalt's weight and drive-type may create issues with braking and stability that are beyond the capabilities of typical RV towing systems.
Consult with a professional RV towing specialist for definitive advice on this specific situation. They can assess your RV and its capabilities and give you a safe and appropriate towing solution if one exists.
