My wife and I purchased our first motorhome, a 2015 FR Forester 2251SLE with the Chevy 4500 chassis, and after 2 outings I realized that I HAD to have a tow car. We decided on the 2015 Fiat 500 POP with manual transmission and it is GREAT. My wife loves driving the Fiat in town when we are at home and I love the 37mpg also.
I had a Blue Ox Base Plate installed at the Fiat dealer. My tow bar is a a ReadyBrute Elite that incorporates a surge brake in the tow bar and I love it, click on the link:

My gas mileage (average 11mpg) has not decreased when flat towing the Fiat. You won't have any regrets.
