2004 Dynamax Grand Sport Columbia, Transmission is the impressive 6spd Allison. This is a one in a million motorcoach. Continuous tender loving care has given this motorhome that intuitive feeling that it has been pampered and well maintained. This was always covered or stored inside when not in use. This used to be my grandparents motorhome. They enjoyed many adventures in it, but they are at that age where it's time for someone else to enjoy adventures together in it.
