The Mercedes-Benz E 320 CDI with a Ace Award Tristar with an actual weight of 1461 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 very good. And also the weight of the Ace with a normally distributed User Payload (200 kg in the caravan and 200 kg in the car including passengers), is pretty good.

Mercedes-Benz E 320 CDI Ace Award Tristar
Actual Weights
Ace Award Tristar: 1461 kg.
Mercedes-Benz E 320 CDI: 1950 kg.
Noseweight: 80 kg.
Actual weight ratio: 75%.
Performance
The engine's performance is generally very good on flat roads (performance score to compare 279 points).
Speeds of 83 mph (134 km/h) to 87 mph (141 km/h) are often quite possible.
There is a lot of power at low engine speeds (score to compare 362 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 12.5 sec.
In the mountains the performance is generally very good (score to compare 343 points).
No problems are to be expected on steep mountain roads (up to 25%). Not even on Hill starts.
On motorway inclines hardly any higher revs are needed.
A speed of 75 mph (121 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 (or B96) driving license.
The caravan is too heavily loaded.
Weight ratio between the laden caravan and the loaded car is 75%. Common in the UK: the weight ratio between the laden caravan and the kerbweight of the car is 83%.
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 80 kg.
Safe speed up to 56 mph (90 km/h).
Stability and safety score to compare is 155 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.
