Perhaps the most famous body on the Royal Tiger coach was the Burlingham Seagull, but Dinky Toys chose the Duple Roadmaster body for their contemporary version, a style that was considerably rarer in full size than were 1:76 scale die cast metal models of it on railway layouts and in toy cupboards. Leyland’s own 44-seat bus and 41-seat coach bodies were built on a large number of Royal Tigers until Leyland's in-house coachbuilders were locked-out at the conclusion of an unofficial industrial dispute in 1954 bringing Leyland bus and coach bodies to an end. Although the 8 ft width was the majority choice most operators chose the vacuum-servo braking system, which was at its limits coping with a fully laden vehicle with an eight-ton unladen weight. Export Royal Tigers were different. Suffix numbers varied more than home market versions as an option for overseas variants was an AEC fluid coupling and air-actuated preselector gearbox combination as on the rival AEC Regal IV. Air brakes were generally offered, vacuum brakes and narrow track were rare options and an air-servo to the Leyland clutch and synchromesh gearbox was offered as standard on all air-braked layshaft-gearbox variants. Omitting suffixes the OPSU series can be tabulated thus:  O stood for overseas and left-hand drive variants had an L prefix to the type code, Hence for example LOPSU2. Customers for the Royal Tiger were found on every populated continent, sales were however particularly high in Europe, the Middle East, South America and Australasia. All overseas markets took the OPSU series save Ireland. In the UK-administered six counties of Northern Ireland the Ulster Transport Authority constructed its own bus and coach bodies on 176 examples whilst cross-border operators Londonderry and Lough Swilly Railway, The Lough Erne Railway and the Great Northern Railway (Ireland) all took Saunders-Roe bodied PSU1 Royal Tigers, all to the rarer width: CIÉ, the Irish Republic's government transport undertaking, after evaluating the coach demonstrator, took wide PSU1 Royal Tigers with their own bodies, bus and coach, these forming the 200-strong U-class. The Irish Army also bought a single example, to transport regimental bands, this was also Saunders-Roe bodied it has a centre entrance is wide, registered ZU5000 and delivered in 1953; it has recently been found by preservationists and is now stored awaiting restoration.
