I don't believe the '07 Equinox is towable 4 down without modification. In fact, I don't even know if it can be towed with modification. You would have to contact Remco to see if a lube pump is available.
Starting in 2009 (I think), a model of the Equinox called the Sport was available that used a different engine/transaxle. The Sport model is towable.
Starting in 2010, the Equinox was redesigned and now all models are towable.
