The MG ZT 135 CDTi 2.0 16v with a Swift Challenger 490 with an actual weight of 1540 kg is in general a good match and suitable for all journeys on all kinds of roads.
The motor preformance of the MG is in general more than sufficient. But the weight of the Swift with a normally distributed User Payload (200 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!

MG ZT 135 CDTi 2.0 16v Swift Challenger 490
Actual Weights
Swift Challenger 490: 1540 kg.
MG ZT 135 CDTi 2.0 16v: 1810 kg.
Noseweight: 85 kg.
Actual weight ratio: 85%.
Performance
The engine's performance is generally good on flat roads (performance score to compare 203 points).
Speeds of 70 mph (113 km/h) to 76 mph (123 km/h) are often quite possible.
There is sufficient power at low engine speeds (score to compare 175 points).
Slightly higher revs (1900 rpm) may be necessary under normal conditions on flat roads.
Acceleration from 0-62 mph (0-100 km/h) is theoretically possible in 21.9 sec.
In the mountains the performance is generally good (score to compare 210 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 (3600 rpm) are needed.
A speed of 60 mph (97 km/h) is usually possible on most motorway inclines.
Weight
The towing limit of the MG is sufficient (check this in your vehicle documents).
The car is too heavily loaded.
Weight ratio between the laden caravan and the loaded car is 85%. Common in the UK: the weight ratio between the laden caravan and the kerbweight of the car is 96%.
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 85 kg.
Safe speed up to 56 mph (90 km/h).
Stability and safety score to compare is 116 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.
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.
