Actual Weights
- Coachman Laser 650: 1810 kg.
- Mercedes-Benz R 320 CDI 4Matic: 2450 kg.
- Noseweight: 100 kg.
- Actual weight ratio: 74%.
Performance
- The engine's performance is generally very good on flat roads (performance score to compare 272 points).
- Speeds of 83 mph (134 km/h) to 88 mph (142 km/h) are often quite possible.
- There is a lot of power at low engine speeds (score to compare 341 points).
- Higher revs (1600 rpm) are usually not necessary on flat roads, under most circumstances.
- Acceleration from 0-62 mph (0-100 km/h) is theoretically possible in 15.4 sec.
- In the mountains the performance is generally very good (score to compare 323 points).
- No problems are to be expected on steep mountain roads. Hill starts are possible on steep slopes up to 23%.
- On motorway inclines hardly any higher revs are needed.
- A speed of 73 mph (118 km/h) is usually possible on most motorway inclines.
Weight
- The towing limit of the Mercedes-Benz is more than sufficient (check this in your vehicle documents).
- If you passed your driving test after 1 January 1997, you will need a B+E driving license.
- Weight ratio between the laden caravan and the loaded car is 74%. Common in the UK: the weight ratio between the laden caravan and the kerbweight of the car is 80%.
- There is a small chance of snaking at higher speeds, strong side winds and thoughtless driving. Even if the combination normally feels stable, the forces by deflection side to side are great at high speed. For drivers with knowledge of, and experience in driving a caravan it is safe to drive, but proper and careful loading is still important! An electronic stability system in the car and / or on the caravan is worth considering.
- Recommended noseweight is 90 - 100 kg.
- Towball limit is 85 kg (Check this on the type plate of your towbar!)
- Safe speed up to 62 mph (100 km/h).
- Stability and safety score to compare is 167 points.
If the caravan starts to snake you should reduce your speed and slow down directly! Lift your feet off the accelerator and brake gradually. Hold the steering wheel into a fixed position.
Conclusion
- Performance is very good.
- If the caravan is well loaded safe driving is possible.
- It's a perfect match!
Influence of User Payload on stability
Weight distribution and noseweight are vital in obtaining a stable caravan.
Distribute the User Payload by yourself in the caravan and the car and then find out the stability rating of your loading configuration.
