I attached it but it only affects the 4-cylinder engine flat tow procedure, not the 6-cylinder engine flat tow procedure.
A good battery charge line and ground line
is mandatory, "good" meaning 12 gauge wire or 14 gauge at the smallest. The Equinox pulls almost 8 amps from the car's battery when configured for towing and that will kill the car's battery in just a few hours without an appropriate-sized battery charging circuit from the motorhome.
Your Winnebago 31G has a GVWR of 14,500 pounds. An Equinox weighs roughly two tons so it needs a supplemental braking system installed as well. Otherwise you have an additional 4,000 pounds of Equinox pushing your (maximum weight) 14,500 pound motorhome every time you stop.
Per DOT requirements, the braking system on any vehicle is only designed to stop the vehicle itself, never anything being towed. Without a supplemental braking system on the Equinox your braking distances will be longer but you may not notice until you hit someone you otherwise would not have hit.
Also, your motorhome will have accelerated wear on its brakes and rotors. You'll pay for the lack of a toad supplemental braking system one way or another.
