As a newbee exploring the potentials of motorhome ownership i am having a hard time getting my head around less than 10mpg,the financial implications of driving to florida from montreal or any other long trip are making me think that motor homes are more than i can afford,I need something that can get 15 to 20mpg,sleep 2 adults and 2 kids and have a bathroom cost $10-25k used,,does such a machine exist?or am i doomed to tenting it..
