I agree SUV's are not SUV's. My wife has a 2016 Subaru Outback...it's called a "wagon" in marketing lit, and the title says "wagon". I have made a few friends unhappy calling their SUV a "wagon" or "minivan". Yes, i do it for the friction and discussion afterwards.
Anyway, point I'm making is I too miss the old wagons that could pull a small trailer. A great pic I have from 1981, when I was a 9 year old lad, is my dad hooking up our 1972 Buick Electra 225, full frame and 455 cubic inch 4 door family car, to our Shasta 29 foot bunkhouse TT (no slide outs!). We had many a family trips in that set up. Don't ask me weights, because I have no idea. But it did have weight distribution set up.
