The Kia Carnival 2.9 CRDi with a Compass Rallye 634 with an actual weight of 1839 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 Kia is in general more than sufficient. But the weight of the Compass with a normally distributed User Payload (200 kg in the caravan and 200 kg in the car including passengers), is quite heavy, but no problem if the caravan is well loaded and the driving speed is not too fast. Remember to load your caravan correctly, insuring that the noseweight of the caravan is sufficient and the weight is distributed properly!

Kia Carnival 2.9 CRDi Compass Rallye 634
Actual Weights
Compass Rallye 634: 1839 kg.
Kia Carnival 2.9 CRDi: 2420 kg.
Noseweight: 100 kg.
Actual weight ratio: 76%.
Performance
The engine's performance is generally fairly good on flat roads (performance score to compare 192 points).
Speeds of 72 mph (116 km/h) to 78 mph (126 km/h) are often quite possible.
There is sufficient power at low engine speeds (score to compare 192 points).
Slightly higher revs (1800 rpm) may be necessary under normal conditions on flat roads.
Acceleration from 0-62 mph (0-100 km/h) is theoretically possible in 29.1 sec.
In the mountains the performance is generally fairly good (score to compare 164 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 higher revs (3800 rpm) are needed.
A speed of 56 mph (90 km/h) is usually possible on most motorway inclines.
Weight
The towing limit of the Kia is sufficient (check this in your vehicle documents).
If you passed your driving test after 1 January 1997, you will need a B+E driving license.
Weight ratio between the laden caravan and the loaded car is 76%. Common in the UK: the weight ratio between the laden caravan and the kerbweight of the car is 83%.
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 90 - 100 kg.
Towball limit is 75 kg (Check this on the type plate of your towbar!)
Safe speed up to 56 mph (90 km/h).
Stability and safety score to compare is 147 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 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.
