We went from an HHR...easy tow...remove one fuse and go....to our new Equinox...same deal...remove one fuse and go....I put a toggle switch on the fuse so I don't even have to remove it...just flip the switch and I'm off....mileage does not register while towing....HHR was 3100 pounds, the Equinox is 3777, but I haven't had it on the scales yet...lastly, look into the ReadyBrute system from Night Shift Auto...it incorporates a piston in the tow bar that works as a braking system for your towed vehicle. Nothing extra to buy......Dennis
