Mr. Don,
Ford makes a lot of cars and trucks for towing as does General Motors. Honda CR-V's up to 2014 can be towed 4 down (AWD or 2WD). We are on our second Honda as they tow so well. Seems as though a lot of the foreign cars are only towable with a manual transmission like Suburu's.
I'm thinking of selling my Honda CR-V as my sister wants to buy it and I would like a better color match to the new motorhome. So, I've been looking at the Lincoln MKX (same as a Ford Edge). The Ford Escape and Lincoln MKC are not towable four down.
The Motorhome Magazine towing guide shows the 2016 Ford Explorer as towable in 2WD and 4WD.
Good luck,
MM.
