We are buying a new motorhom next year . I'm in a pondry about what to buy . Are R v more trubbel than they are worth dose it cost simler to repair as say a auto...trail .i know they only do about ten to gall . And if any ones knows it .Is deasal better than petrol . We own a auto cruise at the moment I get 25/30 to gall and not too bad on repairs . So I need the boys with the Big toys to set me right. John. Linda ...ps sorry if spelling is doggie I'm only 57....lol
