The Renault Trafic 2.0 dCi with a Knaus Sport 420 LD with an actual weight of 1250 kg is in general a good match and suitable for all journeys on all kinds of roads.
The motor preformance of the Renault is in general fairly good. And also the weight of the Knaus with a normally distributed User Payload (200 kg in the caravan and 200 kg in the car including passengers), is very good.

Noseweight: 70 kg.
Actual weight ratio: 63%.
Performance
The engine's performance is generally good on flat roads (performance score to compare 202 points).
Speeds of 71 mph (115 km/h) to 77 mph (124 km/h) are often quite possible.
There is more than enough power at low engine speeds (score to compare 220 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 24.2 sec.
In the mountains the performance is generally good (score to compare 206 points).
No problems are to be expected on steep mountain roads. Hill starts are possible on steep slopes up to 16%.
On motorway inclines the speed drops despite high revs.
A speed of 59 mph (95 km/h) is usually possible on most motorway inclines.
Weight
The towing limit of the Renault 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.
Weight ratio between the laden caravan and the loaded car is 63%. Common in the UK: the weight ratio between the laden caravan and the kerbweight of the car is 69%.
The chance of snaking is small even at higher speeds.
Recommended noseweight is 70 kg.
Stability and safety score to compare is 210 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.
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.
