Created in 1973 to increase access to Canada's national collections, the Mobile Exhibits Programme travels year-round bringing museum exhibits mainly to rural communities which do not have ready access to museum facilities. Display artifacts, works of art, natural history specimens, replicas, models, and dioramas are housed in three caravans, each caravan consisting of three fourteen-meter long custom-fitted highway transport trailers depicting a region of Canada. This paper discusses some of the conservation problems which are associated with road travel. These problems include environmental monitoring, climatic extremes, fluctuating temperature and relative humidity, display mounting, dust, and vibration. -- AATA
