Choosing motorhome accessories: a practical guide to comfort, maintenance and power

The right motorhome accessories can make your travels more comfortable, but the wrong purchase can quickly prove costly. A device might not be compatible with your power system, repair tape may not stick well to a damp surface, or a moisture absorber could be placed in a small space without being checked.

For motorhome owners, caravan owners and camping enthusiasts, there are three common pitfalls to watch out for:

• Choosing power without checking the whole system: a 3000-watt motorhome inverter draws a lot of current from a 12V battery. The cables, fuse and ventilation must all be suitable.
• Ignoring dimensions and connections: a motorhome fridge must not only fit the available space, but also be suitable for 12V or 24V and have adequate ventilation.
• Mistaking marketing claims for guarantees: terms such as “fast cooling”, “long service life” or “waterproof” only tell you so much unless the relevant specifications are clear. Always check the product information, instructions and safety warnings.

Which motorhome essentials are genuinely useful?

A good selection starts with how you plan to use them. You’ll need different camping gear for a weekend at a campsite than for a long trip without a permanent power connection.

1. Check the size, capacity and connection

For power products, the technical specifications are key:

• A motorhome battery lists details such as voltage, capacity in Ah, maximum charge and discharge current, and dimensions.
• A LiFePO4 motorhome battery can combine low weight with a long stated cycle life, but it must be compatible with your charger and onboard electrical system.
• A motorhome inverter converts the battery’s direct current into 230V alternating current. Check the difference between continuous power and peak power.
• A motorhome fridge must suit the available power source. A 12/24V compressor model is not the same as a fridge that runs directly on 230V.

Before buying, measure the available space, allowing for cables and ventilation, and make sure there’s a way to secure the product safely.

2. Consider the material and conditions of use

For outdoor use, the material and preparation matter more than a striking product name. When choosing motorhome repair tape, for example, check:

• the tape’s width, length and thickness;
• whether it is suitable for metal, plastic, glass, EPDM or another surface;
• the temperature range and UV resistance stated in the product information;
• whether it should be applied to a clean, dry surface.

According to the product description, TAPEBEAR Butyl Rubber Tape is 50 mm wide, 5 metres long and approximately 1 mm thick. Its stated uses include RV repairs, windows, roofs and pipes. The manufacturer gives a temperature range of -40 °C to 80 °C. This is information provided by the manufacturer, not a guarantee that it will permanently fix every leak.

3. Think about maintenance and safety

A motorhome moisture absorber can be useful when your vehicle is in storage or in an enclosed caravan, but place it on a stable surface and check the reservoir or saturation level regularly. According to the product information, BISON Vochtvreter Magnet refills are fragrance-free and intended for use in small spaces, caravans and motorhomes. Keep the refill out of children’s reach and follow the warnings about eye contact.

Toys also call for clear safety checks. Motorhome toys with small parts are not suitable for children under three. Also check the age recommendation, material information and any supervision warnings.

Frequently asked questions about motorhome accessories

Which motorhome accessories do I need for my first trip?

Start with practical essentials: power cables, a suitable motorhome battery, a moisture absorber for storage, repair materials, lighting and, if needed, a portable motorhome fridge. Choose everything to suit your vehicle, the space available and the way you plan to camp.

How long does a LiFePO4 motorhome battery last?

Its lifespan depends on the charge level, temperature, charging equipment and how it’s used. Manufacturers sometimes state a number of charge cycles, but this isn’t a fixed service life for every situation. Check the BMS specifications and follow the charging and storage instructions.

Does a motorhome inverter use a lot of power?

That depends on the connected appliance and the inverter’s efficiency. A high-power appliance can draw a lot of current from a 12V battery. Check the stated continuous power and peak power, and switch the inverter off when you don’t need it.
