I think that the Ford Escape with the 2.0L EcoBoost is a good prospect.
One very important issue is that the vehicle needs to be ordered with the factory option for towing.
The equipment can be added later, but it will still be rated 2000 lbs and not 3500 lbs.
The equipment must be setup and programmed in the factory build and as far as I know the dealers cannot accomplish this later, even if the parts are purchased and added.
So..... look for option 536 on the build sheet.
While the kit can be added to the other models the 3500 lb option is dealer installed only. 3500 lb toe limit and 350 lb hitch weight. WDH is also allowable.
This setup has the added module to activate the trailer electronic stabilization and takes care of the trailer lights
hookup for the 4 pin plug.
Since this is based on the Kuga sold in Europe the stabilization is required over there.
Towing capacity over there (for the 2.0L diesel) is 4629 lbs and the 85% is 2880.
The 85% rating of the tow car weight is because extra training and experience is required over that amount.
It is comforting that the 3500 lb rating is using SAE J2807 so you can be fairly confident that it will do what they say it will.
My only point is to get the option factory installed because most dealers have no idea what they are talking about and will happily sell you the package with the stickers on the hitch and it is not the same car.
If I am incorrect then pleas let the others know!
