Bruce, when the OP says "when towing" he really means "being towed". Two different things...as he is using the Equinox (Chevy SUV) behind his motor home. No TT involved at all.
OP, I have the Terrain which is a half sister to your Equinox with the exact same drive train and, of course, same limitations. We typically drive between 60 and 65 and have on numerous occasions gone over 65, but only for short period of times. However, running at a sustained speed over the limitation may not be a problem...but why take the chance?
If I were you, I would just slow down a couple miles per hour... you won't know the difference and neither will your motor home.
