The Mercedes-Benz Vito 115 CDI with a Coachman Laser 640/4 with an actual weight of 1825 kg is in general a good match and suitable for all journeys on all kinds of roads.
The motor preformance of the Mercedes-Benz is in general fairly good. But the weight of the Coachman with a User Payload (159 kg in the caravan and 200 kg in the car including passengers), is quite heavy. Proper and careful loading is essential and don't drive too fast. Remember to load your caravan correctly, insuring that the noseweight of the caravan is sufficient and the weight is distributed properly!

Actual Weights
Coachman Laser 640/4: 1825 kg.
Mercedes-Benz Vito 115 CDI: 2120 kg.
Noseweight: 100 kg.
Actual weight ratio: 86%.
Performance
The engine's performance is generally good on flat roads (performance score to compare 223 points).
Speeds of 76 mph (122 km/h) to 81 mph (131 km/h) are often quite possible.
There is more than enough power at low engine speeds (score to compare 238 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 22.9 sec.
In the mountains the performance is generally good (score to compare 233 points).
No problems are to be expected on steep mountain roads. Hill starts are possible on steep slopes up to 15%, but do require some experience from the driver.
On motorway inclines higher revs (3000 rpm) are needed.
A speed of 63 mph (101 km/h) is usually possible on most motorway inclines.
Weight
The towing limit of the Mercedes-Benz is 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 86%. Common in the UK: the weight ratio between the laden caravan and the kerbweight of the car is 95%.
The risk of snaking at higher speeds, strong side winds and thoughtless driving exist. Even if the combination normally feels stable, the forces by deflection side to side are so great that it could be dangerous. Only if the driver has knowledge of and experience in driving a caravan it should be safe to drive. Proper and careful loading is essential! An electronic stability system in the car and / or on the caravan is recommended.
Recommended noseweight is 100 kg.
Safe speed up to 56 mph (90 km/h).
Stability and safety score to compare is 125 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 fairly good.
Proper and careful loading is still important!
It's a perfect match!
Influence of User Payload on stability
Weight distribution and noseweight are vital in obtaining a stable caravan.
