Making [caravans] more stable is readily possible by design, loading, and tow vehicle use and choice. This article by Collyn Rivers explains how. It also provides practical guidelines for buying a [caravan] and tow vehicle, their loading and on-road usage. For a full technical explanation of why rigs can be unstable please see my [Caravan] and Tow Vehicle Dynamics/. See also Why Caravans Roll Over/
Health & Safety
Overweight RVs – a police point of view
This article is a précis of my discussion with Sergeant Graeme Shenton (Orbost Police Station) about two years ago. Sergeant Shenton is a caravanner and is taking a leading role (via ongoing road side checks etc) in establishing accurate data on the extent of overladen RVs on Australian roads. Most rigs checked are [caravans] – as there are about six times more of those than campervans and motor homes.
Caravan nose weight – it’s vital for safe towing
The current (February 2018) Australian RV rules and regulations are outlined here by Collyn Rivers of RV Books. Those for trailers under 4500 kg (9920 lb) will change in late 2018 but details are not yet available
Blade fuse problems in caravans – they may burn or melt
Blade fuse problems in [caravans] include fuses and fuse holders burning or melting. Fire risk is high because the fuses may continue to conduct. Ongoing current flow, however, may heat the fuse holder to burning point. This article by RV Books explains why and how to overcome the risk.
Towing Without a WDH – Weight Distributing Hitch
A weight distributing hitch is not needed if the laden weight of the tow vehicle is equal to or exceeds that of the laden [caravan]. Nor is a weight distributing hitch needed for any trailer under about 4 metres.
RV supply cables – choices of current capacity and length
This article shows the sizes and lengths of electric supply cables for [caravans] and motor homes legally required in Australia and NZ.
Lightning risk in RVs – how to reduce that risk
Lightning frightens but lightning risk in [caravans] is very low. That risk however is far from random. Here’s how to reduce it yet further.
LP Gas risk in caravans – deaths & brain damage still occurs
A major LP gas risk in [caravans] is carbon monoxide build up. Low levels cause brain damage, and death at high levels. Here’s how to eliminate the dangers. A carbon monoxide build up as a direct result of burning LP gas in any inadequately ventilated confined space. The risk in RVs is high enough to take seriously. Since 2009 about 12 people (in Australia alone) died in [caravans] due to the above. In the USA it typically exceeds 1000 people a year. Far more have suffered brain damage.
Safe RV heating – use diesel or LP gas
This article explains safe [caravan] and motor home heating using diesel or gas. It explains how it works, what is available and how to safely install it. To ensure safe [caravan] and motor home heating it must be done correctly. Apart from a build-up of carbon monoxide, there is a risk of oxygen deprivation. For a full technical and medically-referenced explanation see article Gas Risk in [Caravans].
Battery ventilation is vital – why take any risk?
All lead acid batteries, AGMs and gel cells, generate explosive gas. Even though most are sealed, makers stress that battery ventilation is vital still. Confusion exists over this. Around 2000, some battery makers began to claim that no ventilation was required. Or, ventilation, is advisable but not necessarily essential. They withdrew this advice, however, shortly after. Many batteries thus have a warning notice as below.
