    A refined 4 berth caravan with a versatile side dinette layout.

    The Bailey Unicorn Madrid S4 is a single axle caravan featuring a 3 to 4 berth layout, built using Alu-Tech timberless construction. It is distinguished by a side dinette that converts to bunk beds and a full-width rear washroom. With a 7.11m length and a 1496kg MTPLM, it includes high-specification features such as Alde central heating and a vertical front infinity window. Used prices typically range between 17500 and 24000.

    • Single axle chassis with a 7.11m overall length.
    • Alu-Tech timberless bodyshell construction.
    • Side dinette layout that converts into bunk beds.
    • Full-width rear washroom with a separate shower cubicle.
    • Alde hydronic central heating and water system.

    Worth knowing: The 1496kg MTPLM requires a tow car with sufficient power compared to entry-level caravans. Bunk bed dimensions may be restrictive for taller teenagers. Front locker storage capacity is reduced compared to previous Unicorn generations.

    Buying a Bailey Unicorn Madrid S4

    Who it suits

    • • Couples who desire a spacious side dinette for lounging.
    • • Small families requiring flexible bunk bed sleeping arrangements.
    • • Year-round tourers who benefit from hydronic central heating.

    Reasons to consider it

    • • The vertical infinity window creates a bright, open lounge environment.
    • • High-specification kitchen and washroom fixtures provide a premium feel.
    • • The timberless construction offers improved thermal insulation for winter use.

    What to check

    • • Confirm the operation of the Alde heating system and fluid levels.
    • • Inspect the condition of the Alu-Tech seals and external body panels.
    • • Verify the functionality of the Truma solar panel and off-grid charging.
    • • Check the condition of the Dometic refrigerator and Thetford oven.

    Worth knowing: Payload is limited to 155kg, requiring careful management of heavy equipment. The vertical front window provides significant light but may affect privacy in certain pitches.

    Compare the Bailey Unicorn Madrid S4 with similar models

    ModelBerthsMTPLMLengthTypical price
    Bailey Unicorn Madrid S441496 kg7.11 m£17,500 to £24,000
    Bailey Unicorn Deluxe Vigo41500 kg7.34 m£18,500 to £33,995
    Bailey Unicorn Deluxe Cadiz41500 kg7.34 m£17,500 to £33,500

    The Bailey Unicorn Madrid S4 occupies a specific niche in the Unicorn range, offering a 7.11m length that is shorter than the 7.34m Unicorn Deluxe Cadiz or the 7.37m Cabrera. While it shares the 1496kg MTPLM of the Unicorn Deluxe Madrid, it provides a different balance of internal space and towing weight. It remains a competitive choice for those prioritising a side dinette over fixed bedding, though buyers must weigh the 155kg payload against their touring requirements.

    Worth knowing: Specifications and prices can vary by model year, trim and optional equipment.

    Ownership and Maintenance Tips

    • Utilise the 2.28m width to ensure comfortable clearance when navigating narrow lanes.
    • Monitor the Truma solar panel output to maintain battery health during storage.
    • Regularly service the Alde system to ensure efficient heat distribution throughout the 7.11m cabin.

    Common mistakes to avoid

    • • Assuming the bunk beds are suitable for all adult heights.
    • • Underestimating the towing requirements for the 1496kg MTPLM.

    Worth knowing: Ensure the 155kg payload is not exceeded when fitting optional extras like motor movers.
