The 40 litre Aquaroll is manufactured to the same high specification as the 29 litre version but with the added advantage of a facility to connect via the mains adaptor kit directly to a mains water supply. Even without the mains supply facility the extra capacity is a must in modern caravanning. The side opening can also be used as a convenient filling point when in use as a conventional water carrier. High quality tyres on deep rims give excellent ground clearance. Filler tube also included
