Is the Bailey Unicorn Series 4 Cartagena a practical luxury caravan?
The Bailey Unicorn Series 4 Cartagena is a high-specification twin-axle caravan designed for four berths. It features a dedicated rear master suite with a transverse island bed and a full-width end washroom. Built on the Alu-Tech bodyshell, it includes premium components such as Alde central heating and a 190-litre fridge-freezer, making it suitable for long-term touring and seasonal use.
- Twin-axle chassis with AL-KO ATC trailer control and AKS 3004 stabiliser.
- Transverse island bed layout with a full-width end washroom.
- Alde hydronic programmable radiator heating system.
- Dometic 190-litre large capacity fridge and freezer.
- Truma 100-watt solar panel and TRACKER recovery system.
Worth knowing: The 1687kg MTPLM necessitates a heavy, powerful tow vehicle. A 7.91 metre total length may require a motor mover for tight pitches. Insurance premiums are typically higher for twin-axle models.
Buying a Bailey Unicorn Series 4 Cartagena
Who it suits
- • Couples seeking a permanent rear bedroom with domestic-style washroom facilities.
- • Year-round tourers who require the silent efficiency of Alde radiator heating.
- • Drivers with heavy tow vehicles who prioritise twin-axle stability.
Reasons to consider it
- • The 7.91 metre length provides a spacious, apartment-like interior layout.
- • High-specification safety features including ATC and a TRACKER system.
- • Excellent thermal performance for winter use via the Alu-Tech construction.
What to check
- • Confirm the service history to maintain the Alu-Tech bodyshell integrity.
- • Test the Alde heating system across all programmable settings.
- • Verify the operation of the 100-watt solar panel and PIR intruder alarm.
- • Check the condition of the 190-litre Dometic fridge-freezer seals.
Worth knowing: Payload is limited to 160kg, which must cover all personal belongings and optional extras. The 2.28 metre width is standard for the range but narrower than some modern 8-foot wide alternatives.
Compare the Bailey Unicorn Series 4 Cartagena with similar models
| Model | Berths | MTPLM | Length | Typical price |
|---|---|---|---|---|
| Bailey Unicorn Series 4 Cartagena | 4 | 1687 kg | 7.91 m | £21,000 to £28,500 |
| Bailey Unicorn Cadiz | 4 | 1600 kg | 7.34 m | £18,000 to £34,000 |
| Bailey Unicorn Vigo | 4 | 1600 kg | 7.34 m | £17,000 to £34,000 |
The Bailey Unicorn Series 4 Cartagena sits at the top of the Unicorn range, offering a 7.91 metre twin-axle platform that prioritises a fixed bedroom and large washroom. While the Unicorn Barcelona shares the same external dimensions, the Cartagena is distinguished by its transverse island bed. For buyers restricted by towing limits, the single-axle Vigo or Cadiz offer similar luxury features in a shorter 7.34 metre frame, though they lack the internal floor space and 190-litre fridge capacity found in this flagship model.
Worth knowing: Specifications and prices can vary by model year, trim and optional equipment.
Ownership and Maintenance Tips
- Utilise the twin-axle stability for smoother motorway towing in crosswinds.
- Ensure the Alde heating fluid is replaced according to manufacturer intervals.
- Make use of the 100-watt solar panel to maintain battery health during storage.
Common mistakes to avoid
- • Overloading the 160kg payload, which is relatively modest for a caravan of this size.
- • Attempting to manoeuvre the 7.91 metre length manually on soft ground.
Worth knowing: The 1687kg MTPLM is a significant weight; always verify your vehicle's towing limit.
Alternatives to the Bailey Unicorn Series 4 Cartagena
The Cadiz offers a 7.34 metre length for buyers who prefer twin fixed single beds over the Cartagena transverse island bed.
Bailey Unicorn VigoFor those seeking a shorter 7.34 metre single-axle model, the Vigo provides a transverse island bed at a lower MTPLM.
