The Opel Signum 2.2 Dti with a Bailey Discovery Mars with an actual weight of 1193 kg is in general a good match and suitable for all journeys on all kinds of roads.
The motor preformance of the Opel is in general more than sufficient. And also the weight of the Bailey with a normally distributed User Payload (200 kg in the caravan and 200 kg in the car including passengers), is very good.

Performance
The engine's performance is generally fairly good on flat roads (performance score to compare 195 points).
Speeds of 69 mph (112 km/h) to 76 mph (122 km/h) are often quite possible.
There is more than enough power at low engine speeds (score to compare 207 points).
Slightly higher revs (1700 rpm) may be necessary under normal conditions on flat roads.
Acceleration from 0-62 mph (0-100 km/h) is theoretically possible in 24 sec.
In the mountains the performance is generally fairly good (score to compare 193 points).
No problems are to be expected on steep mountain roads. Hill starts are possible on steep slopes up to 14%, but do require some experience from the driver.
On motorway inclines higher revs (3100 rpm) are needed.
A speed of 58 mph (94 km/h) is usually possible on most motorway inclines.
Weight
The towing limit of the Opel is more than sufficient (check this in your vehicle documents).
If you passed your driving test after 1 January 1997, a B driving license is enough.
Weight ratio between the laden caravan and the loaded car is 62%. Common in the UK: the weight ratio between the laden caravan and the kerbweight of the car is 70%.
The chance of snaking is small even at higher speeds.
Recommended noseweight is 70 kg.
Stability and safety score to compare is 215 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 more than sufficient.
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.
