suspension has requirements that are very different from tow vehicles. This is only too often misunderstood. Here’s why and what it should be.

For safe towing, a tow ball weight right.

The maximum weight safe to tow depends on what tows it. This article by Collyn Rivers explains why – and how to know what it is.

Fifth wheel and motor home sales.

You can obtain gross combined mass upgrades for most SUVs. Depending on make and model, these add 300-500 kg. It makes sense to do this. Carrying that extra mass results in a safer ratio of laden tow vehicle weight to laden weight.

In the early 1900s, trailers with central axles, towed by trucks with overhung hitches, were unstable. This escalated as towing speeds increased. Fruehauf (USA) realised hitch overhang imposed lateral forces on tow vehicles. As trailers yawed clockwise, that overhang caused tow vehicles to yaw anti-clockwise. And vice versa. The longer that hitch overhangs, the greater ...

Knowing how to locate mass correctly along the length of a safely – and why and how it matter doing so is vitally important.

The overhung hitch of a 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.

Long end-heavy have a need for a Weight Distributing Hitch (WDH). For all, though, it inherently reduces tow vehicle stability. Here’s how and why.

Conventional hitches overhang the worse the effect. It is undesirable at low levels. ...

Reducing sway (yaw) necessitates minimising its causes – and only then adding devices promoted as reducing it. This article shows why and how.

On the surface, the Australian RV industry is healthy. But underneath all is far from well. A  great deal needs changing. There are lots to do. RV Books explains the RV industry changes needed.

A 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. 

A weight distributing hitch is not needed if the laden weight of the tow vehicle is equal to or exceeds that of the laden . Nor is a weight distributing hitch needed for any trailer under about 4 metres.

Tow ball weight pushes down the rear of the tow vehicle – thereby increasing the weight on its rear tyres. A WDH, in effect, is a semi-flexible springy beam that levers back up the rear of the tow vehicle and levers down its front. In doing so, however, it reduces the imposed load on the ...

Correct weight distribution hitch setting up compensates tow vehicle front end lift but introduces instability if too tight. Here’s why.

Wheels falling off trailers, wheel studs breaking and wheel nuts loosening still happens. Here is why it happens, and how to prevent it. Wrecked wheel bearings and fractured stub axles are also common. That fastenings such as wheel nuts may be caused, not just permitted, to loosen is rarely covered in engineering training. The causes ...

Twelve-volt systems may be twin-wire or chassis return. Twin-wire is usually best. This article explains why – and which to choose to avoid problems.

Taking 12 volts dc from 24 volts dc can ruin the batteries in a 24 volt system. Here’s how to do it effectively and safely. There are two main ways. The choice depends mainly on the peak current needed: for example the plus 130 amps for a typical microwave oven limits choice to the equalising ...

AGM batteries for , camper trailers, motor homes charge faster and deeper than lead acids and are more rugged mechanically and electrically. They have far less internal discharge. If initially fully charged, they retain 60% or more for over 12 months (except in very hot areas).

Battery charging and battery chargers are often misunderstood – causing batteries to die before their time. This article explains why and how to avoid it.

Battery charging via generator is often slow and shallow or barely works at all. This article shows just why, and how to find and fix the causes.

Blade fuse problems in 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.

Circuit breakers and fuses in both cut the current, but in different ways. Here’s how to know which best suits circuits and appliances protected. Those for 230 volt grid or inverter supplied circuits must be specified and installed by a certified electrician – who will install circuit breakers etc anyway. Circuit breakers and fuses for ...

Initial charging of a deeply discharged battery is generally limited to a basic dc-dc charger’s capacity: not the alternator’s. Dc-dc chargers under 20 amps thus usually take longer to charge close to flat batteries to half charge. Thereon, charging is hugely faster.

Electrical converter problems in and motor homes worldwide. They are thus not suitable for RVs free camping.

Electrical converters in RVs supply 12 volts from 230 volt power. They work well from 230 volts, but not for long-term camping. Here’s how to fix the problem.

Fuel cells for are non-polluting and ultra-quiet. Whilst initially promising their initial and running costs still excludes general RV use.

Using grid connect solar modules for RVs is readily done but needs an MPPT regulator. This article by Collyn Rivers explains how and why it is done.

Imported RV electrics are often not fully compliant. Their owners often wrongly believe they are. They cannot legally be sold unless remedied.

Interconnecting batteries in series or parallel is totally feasible. But its best to know how it works – and the limitations of each. Collyn Rivers explains.

Buying inverters for can confuse. Prices vary for products that may seem identical but are not. Here’s what to buy.

Lead acid batteries for are still a viable buy. They are made in different shapes, sizes and capabilities. All work in a basically similar way. Energy is stored within them as a result of electro-chemical reactions between lead plates and a water/acid mix (called electrolyte). They are charged by imposing a voltage across them that ...

Despite their very small batteries LiFePO4 jump starters really do work. This article by Collyn Rivers explains how and why. A lot of power (the rate at which energy is used) is needed. The amount of energy (the ability to perform work) required, however is surprisingly small. In the days of vintage cars, a strongish ...

Lighting for has changed. Now, by far the most practical and least energy drawing are LEDs (light emitting diodes). This article shows why.

To make fridges work as claimed, and draw less energy, is cheap, simple and easy. Many can be transformed. This article shows how.

Microwave oven power draw is far greater than many users think. In this article, RV Books’ Collyn Rivers explains why – and how. This is a particular problem in and motor homes. Their deep cycle lead acid batteries cannot sustain the energy draw they require. AGM and lithium-ion batteries are thus better suited.

Quietening water pumps is simple to do at no or trivial cost. This article from RV Books’ Collyn Rivers shows how.

Before 2000 or so most alternators produced 14.4 – 14.7 volts, and a few close to 15 volts. This situation changed in 2014 in the quest to reduce emissions. Reducing alternator voltage assists, but introduces problems if the alternator also charges RV batteries. This article by Collyn Rivers explains what causes these alternator charging problems ...

RV batteries store energy from your RV’s or tow vehicle’s alternator and solar modules and grid or generator power via a battery charger. This article explains all about the many types of battery now available.

Solar is now so cheap that the main limitation is the space available for the solar modules. It is not possible to have too much solar. Ample solar prolongs battery life. It also and ensures at least some output during overcast days. There is no risk of overcharging, nor overloading the associated solar regulator. That ...
