Re: 1997 allegro bus
Welcome,
Fast is a relative thing, we have 45 gallon Black and gray, black goes for about 2-3 weeks. Gray we get about 7-10 days being real conservative in use and I am assuming are talking boondocking. Some things we do are wash dishs in a container and dump this outside. Also when getting hot water to the shower we use a bucket then use this water for a black flush, has double duty here saves water and tank space.
