Thanks for the replies. I had previously looked up the max towing capacity of the Equinox with its 3.0 V6 and I assumed, without looking, the Mazda would be similar if not greater. I'm surprised and disappointed to know it's 2,500 lbs with the 3.0, extended cab, and 5-speed manual. After seeing Old Biscuit's notations, I searched it up and he is of course correct. I had just assumed the Equinox would be the lesser of the two.
But it's of little matter: I want a lightweight unit even though most of the towing will be by the Superduty. Anticipation of using the car or the little truck are strictly short-hauls within NC and nearby VA.
Good to know the nomenclature on cargo (CCC), where the dry weight + CCC should be expressed as GVWR.
All of this fits my general desire for a simple, Spartan unit. Can't get but so fancy at <2,200 lbs or so, it seems.
