What gets better gas mileage Class A or Class C?

A 40-ft Class A consumes 18-29 litres/100 km (7-13 mpg). A smaller Class C can expect to get 16-23 litres/100 km (14-18 mpg); while a Class B gets a more thrifty 11-13 litres/100 km (18-25 mpg) or better. The same goes for a trailer or fifth wheel – the smaller the unit, the less gas or diesel is consumed. Pack less.
