Why caravans sway and roll over – how to prevent it
Caravans towed by an overhung hitch sway and may overturn. Over 250 did so in the first six months of 2018. This article explains why caravans sway and roll over – and how to prevent it.
Gross Combined Mass Upgrades
You can obtain gross combined mass upgrades for most SUVs. Depending on make and model, these add 300-500 kg (660-1100 lb). It makes sense to do this. Carrying that extra mass results in a safer ratio of laden tow vehicle weight to laden caravan weight.
Mechanical sway-control has little value at speed
The overhung hitch of a caravan tow vehicle can cause (not just permit) a caravan to sway. This sway annoys at low speed and is dangerous at high speed. Until recently attempts to limit such sway rely on friction to dampen and ideally prevent it. Unfortunately, mechanical sway-control has little value at speed.
RV Accident Data (Australia)
The number of accidents that involve cars towing caravans is no higher than cars generally, but the nature and physics involved in the now 400 or so a year that jack-knife (with many rolling over) are unique. No other on-road combination has this type of accident.

Tow Vehicle/Caravan Weight Ratio Explained
A caravan heavier than its tow vehicle is like a dog with an overweight tail, it may sway so much its tow vehicle cannot control it. Swerving strongly at speed to avoid a head-on collision induce this. So too may a strong side wind gust. That wind may be natural or from a close passing truck.
Overhung Caravan Hitches
Conventional caravans are towed via an overhung hitch attached to the rear of the tow vehicle. This is an inherently unstable combination. A side force on a caravan causes swaying. Caravan swaying is undesirable. Furthermore, at speed, it is dangerous The longer caravan hitches overhang the worse the effect. It is undesirable at low levels. It is dangerous at high levels. And even more so at high speeds. This RV Books article explains why.
Loading a Caravan Safely
Knowing how to locate mass correctly along the length of a caravan is vital. That applies both to its design and the owner’s loading. This article shows the safe approach to loading a caravan – and why and how it matter doing so is vitally important.
10 Tips for Safe Caravan Towing
Caravans and their tow vehicles have much the same accident rates as other forms of motor transport. Their main type of accident, jack-knifing and roll-over, however, are different. Here are ten tips for safe caravan towing.
