Our Sunnybrook now ten years old, recently had the old style Thetford plastic toilet refused to hold water in the bowl. Ordered a brand new Aqua-Magic II China Bowl unit. The old unit had the plastic hose with the crimped on fittings, what a pain getting those off. The plumbing layout for the new unit was different from the old piece. After fighting with a new hose run, the unit is finally end. Same unit we have in the Crusader 270RET. The china bowl sure makes a big difference, Camping World had the unit on Sale for $142.00, normally $205.00.
