The Dennis SS series is a fire engine built by Dennis, it was produced from early 1980s until 1990s. The Dennis SS was almost identical with the previous RS model. It incorporated the same cab design, engine and transmission, except the SS had a tilting cab which made maintenance and overhaul much easier. It could be fitted with a variety of bodies by Dennis and other coachbuilders such as JDC, Carmichael and Fulton Wylie.
