my parents tow a 1410kg bailey pagaent champagne with a kia sedona and we just got 22mpg mostly on motorways, this might not sound alot but when you look at the weight of the car on its own (2 ton) then on top of that full awning, annexe, trolley jack, 3 adults, 3 kids, luggage i personally think it is good. the car has is a 2.9td.
