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 tow vehicles rear tyres and partially restored it on its front tyres. Reducing the load on the tow vehicle’s rear tyres reduces their ‘cornering ability’. This is why a weight distributing hitch limits cornering.
Variable voltage alternator problems with caravans and motor homes arise when charging auxiliary batteries. Here’s why and how to fix them. These alternators are, in particular, installed on many post-2013 vehicles.
TV interference from LEDs is an issue worldwide. It is mostly caused by LEDs in the same home (or RV) as the TV. This can be checked by turning them off. Another indicator of TV interference from LEDs is good daytime reception until lights are turned on. In the worst cases, TV reception is unwatchable, or not even obtainable.
Caravan fridge problems are due to poor ventilation, inadequate cable size and/or insufficient power to drive them. Here’s how to fix them.
Buying inverters for caravans can confuse. Prices vary for products that may seem identical but are not. Here’s what to buy.
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.
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 55 kg girl could hand crank start a 4.5 litre Bentley with relative ease.
Lithium batteries in caravans and motorhomes pack a lot of energy but need specialised knowledge to use safely and reliably. Here’s how and why – and how to install and use them.
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 caravans 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.
AGM batteries for caravans, 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).
