Is the Dethleffs Alpa I 9820-2 a capable luxury tourer?
The Dethleffs Alpa I 9820-2 is a premium A-class motorhome designed for long-term touring, featuring a distinctive rear U-shaped lounge and a 5000kg MTPLM. Built with a heated double floor and Alde central heating, it provides genuine year-round capability for two to four people. Its 8.58m length and 850kg payload accommodate significant equipment, including e-bikes in a 250kg-rated rear garage.
- Rear U-shaped lounge layout with panoramic windows
- Lengthwise drop-down bed system over the cab area
- Heated double floor construction for four-season use
- Alde central heating system fitted as standard equipment
- AL-KO low-frame chassis and 850kg payload capacity
Worth knowing: The 5000kg MTPLM requires a C1 category driving licence. External length of 8.58m may restrict access to some smaller UK sites.
Buying a Dethleffs Alpa I 9820-2
Who it suits
- • Couples seeking a spacious apartment-style layout for extended trips.
- • Winter tourers requiring high-specification thermal insulation.
- • Owners with a C1 licence who need a high 850kg payload.
Reasons to consider it
- • The rear U-shaped lounge offers a residential social space.
- • Lengthwise drop-down beds provide easier access than width-ways alternatives.
- • The 250kg garage capacity is suitable for heavy leisure equipment.
What to check
- • Confirm the specific berth configuration as this model supports two to four people.
- • Verify the operation of the 142L fridge-freezer and integrated oven.
- • Inspect the condition of the AL-KO low-frame chassis.
- • Check the service history of the Alde central heating system.
Worth knowing: The 5000kg GVW is a significant weight threshold for UK driving licences. A width of 2.33m and height of 3.04m require careful route planning.
Compare the Dethleffs Alpa I 9820-2 with similar models
| Model | Berths | Maximum weight | Length | Typical price |
|---|---|---|---|---|
| Dethleffs Alpa I 9820-2 | 4 | 5000 kg | 8.58 m | £115,000 to £185,000 |
| Knaus SUN I The exclusive one | 4 | 5000 kg | 8.82 m | £115,000 to £185,000 |
| Swift Kon-Tiki 784 180BHP Auto | 4 | 5000 kg | 8.84 m | £85,000 to £135,000 |
The Dethleffs Alpa I 9820-2 occupies a specific niche in the A-class market, focusing on a rear-lounge layout and a 5000kg MTPLM. While alternatives like the Knaus SUN I offer a longer 8.82m body at the same weight, the Alpa prioritises its internal U-shaped social hub and double-floor thermal performance. The choice between these models often depends on whether the buyer prefers the Alpa's specific 8.58m footprint or the slightly longer dimensions of its competitors.
Worth knowing: Specifications and prices can vary by model year, trim and optional equipment.
Ownership and Maintenance Tips
- Utilise the heated double floor for storage of temperature-sensitive items.
- Regularly test the Alde heating system to ensure four-season readiness.
- Monitor the 850kg payload when adding heavy accessories to the garage.
Common mistakes to avoid
- • Attempting to drive without a C1 licence due to the 5000kg GVW.
- • Overloading the rear garage beyond its 250kg specific limit.
Worth knowing: The 8.58m length requires awareness of overhangs during tight manoeuvres. Payload must be managed within the 5000kg limit despite the generous 850kg allowance.
