One of the main ingredients to avoiding the above situations is to make sure your caravan is loaded correctly and everything is stowed and securely fastened. Ideally the laden weight must not exceed 85% of the gross weight of your vehicle. Heavier items should be stowed around the wheel axles where possible.
Having good stabilisers fitted should go along way towards helping with swerving and pitching but should only be classed as additional safety feature (some come fitted as standard0).
There are commonly three areas of instability. Pitching can occur after passing over holes in the road, going over speeds humps or where there is a severe dip in the road.
Snaking or horizontal movements of your caravan mainly occur by travelling at high speeds and can also be linked with travelling over potholes, swerving suddenly and an odd gust of strong wind. Gently ease off your accelerator and start braking softly when it is safe to do so.Severe pitching or swerving may lead to a roll, this is when the wheel lifts and leaves the ground. This is a dangerous situation and some causes can be attributed to heavy braking with severe swerving. A poorly or over loaded caravan can also be a contributing factor. test
