The Ford Focus 1.8 TDDi with a Lunar Zenith 4 with an actual weight of 1145 kg is in general a good match and suitable for journeys on most kinds of roads, sometimes with some limitations in the mountains.
The motor preformance of the Ford is in general sufficient. And also the weight of the Lunar with a normally distributed User Payload (200 kg in the caravan and 200 kg in the car including passengers), is good.

Noseweight: 70 kg.
Actual weight ratio: 73%.
Performance
The engine's performance is generally fairly good on flat roads (performance score to compare 161 points).
Speeds of 64 mph (103 km/h) to 70 mph (113 km/h) are often quite possible.
There is only moderate power at low engine speeds (score to compare 105 points).
Slightly higher revs (2200 rpm) may be necessary under normal conditions on flat roads.
Acceleration from 0-62 mph (0-100 km/h) is theoretically possible in 28.5 sec.
In the mountains the performance is generally sufficient (score to compare 141 points).
No problems are to be expected on steep mountain roads but the performance is not that great. Hill starts are possible on steep slopes up to 11%, but do require some experience from the driver.
On motorway inclines the speed drops despite high revs.
A speed of 53 mph (85 km/h) is usually possible on most motorway inclines.
Weight
The towing limit of the Ford is 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 73%. Common in the UK: the weight ratio between the laden caravan and the kerbweight of the car is 84%.
The chance of snaking is relatively small at normal speed, if the caravan is well loaded.
Recommended noseweight is 70 kg.
Safe speed up to 62 mph (100 km/h).
Stability and safety score to compare is 180 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 sufficient.
Safe driving is possible.
It's a good match, sometimes with some limitations in the mountains.
Influence of User Payload on stability
Weight distribution and noseweight are vital in obtaining a stable caravan.
