Claims for dual-cab ute towing capacity mislead caravan buyers. That ute must weigh enough to keep a caravan steady. If not, the caravan tail wags the towing dog.
That caravans roll-over yet most vehicles don’t show caravan dynamics is not understood or is ignored. Caravan dynamics simply explained tells why. The main cause is that hitch extending from the tow vehicle’s rear. It not only allows but causes both tow vehicle and caravan to sway (yaw). Worse – if one yaw’s clockwise it causes the other to sway anti-clockwise. The further the tow ball behind the tow vehicle’s rear axle, the greater that effect.
Do caravans need independent suspension is a marketing rather than an engineering issue. This article explains why caravan beam axles are generally better.
A conventional caravan must always be a compromise. This is because it is towed via hitch at some distance behind the tow vehicle’s rear wheels. If that vehicle sways clockwise, that hitch overhang causes (not just permits) the caravan to sway anti-clockwise. If the caravan sways clockwise, it causes the tow vehicle to sway anticlockwise. is essentially an unstable concept but safe within limits.
The maximum caravan weight safe to tow depends on what tows it. This article by Collyn Rivers explains why – and how to know what it is.
Long end-heavy caravans have a need for a Weight Distributing Hitch (WDH). For all, though, it inherently reduces tow vehicle stability. Here’s how and why.
Caravan Tare Weight issues mainly arise about what’s included and what’s not. Water is not, nor may be optional extras. This article reveals all.
Correct weight distribution hitch setting up compensates caravan tow vehicle front end lift but introduces instability if too tight. Here’s why.
Reducing caravan sway (yaw) necessitates minimising its causes – and only then adding devices promoted as reducing it. This article shows why and how.
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.
