Suggestions on what vehicle to pull 18-20' trailer?

Have a look at the door sticker for maximum tow capacity then take 80%. If the trailer is within that you are good to go if the tow vehicle is properly set up. You can go higher but after our first towing experience I don't recommend it.

Door stickers don't have towing capacity.

I would recommend a full size vehicle of some kind, not the Durango. Any of the other SUVs you've mentioned would probably be fine.

$15k would buy 2-3 SUVs capable of towing the trailer you seek to tow.
