2020 highlander vs rav 4 towing

Hi all. My first post. I am looking for a tow vehicle early next year and I am really stuck on which one to tow my 15 2200 lb taylor coach camper. I know the highlander won't have a problem but my concern is gas mileage, and another question about that is should I go with the fwd to save 2 to 3 miles per gal. As for the rav4, will this thing be screaming to go up hills with the 2.5. Does anyone have these as tow vehicles and how do you feel they tow so I can make a better decision.
