Having upgraded to a 2020 45' Allegro Bus OPP and have just had an etrailer tow system installed for our 2020 Chevrolet Equinox.
What precisely did etrailer install, since they sell several systems for the Equinox?
Which tow bar?
Which supplemental braking system?
What did they install for a battery charge line?
Without that information all you can get is general information and tips.
So I'll offer one general tip.
As you know, both tow bar arms must be locked prior to towing the car. The problem is that usually only one arm will lock because the car is a bit off-center.
To get the other tow bar arm locked faster, turn the steering wheel one-half turn in the direction of the unlocked
arm. As soon as the car starts to move, it will steer towards the unlocked arm, extending it and locking it.
