After 10 years of towing 2 seat Miatas, we are getting set up to tow a 2011 low mileage (11,000) Equinox that my wife recently inherited.
From what I could find on-line and in the manual, the un-laden Equinox weighs between 3,700 and 4,000 pounds. Not the 5,000# that you quoted.
We'll use a Roadmaster base plate as that is what our tow bar is.
In setting up your Eq', what Aux Brake are you using? Charge line?
Are you pulling the fuse or using a switch?
How did you wire the tail lights?
I'm looking at similar RV graphics to put on the white Eq'.
Now we'll be able to take the g-kids with us...
