Caravan Mover Weights Explained: How It Impacts Your Towing Payload

For any dedicated caravanner, weight is a constant consideration. From choosing lightweight gas bottles to debating whether you really need to pack that extra awning, managing your caravan’s payload is an essential part of safe and legal towing.

When you decide to upgrade your touring experience by investing in a motor mover, one of the first questions you will likely ask is: “How much does a caravan mover weigh, and how will it affect my payload?”

It is a crucial question. A motor mover is a heavy-duty piece of mechanical engineering, and adding it to your chassis means you will have slightly less allowance for your personal belongings. In this guide, we will break down exactly how much weight you can expect a mover to add, how to calculate your remaining payload, and why choosing a premium brand like Powrtouch ensures you get maximum power for minimal weight penalty.

Understanding MTPLM and MIRO

Before you can calculate the impact of a caravan motor mover, you need to understand two vital acronyms found on your caravan’s weight plate (usually located near the door or in the front locker).

1. MIRO (Mass in Running Order) This is the weight of your caravan as it leaves the factory. It includes the standard fixtures and fittings, but it is essentially “empty” of your personal gear, water, and aftermarket accessories.

2. MTPLM (Maximum Technically Permissible Laden Mass) This is the absolute maximum legal weight your caravan is allowed to be when fully loaded and hitched to your tow vehicle. Exceeding this weight is illegal, dangerous, and will invalidate your insurance.

The User Payload Your available payload is the difference between these two numbers (MTPLM minus MIRO). This payload allowance must cover your clothes, food, gas bottles, leisure battery, water, and any dealer-fitted accessories – including your motor mover.

How Much Does an Average Caravan Mover Weigh?

Because motor movers require powerful electric motors, heavy-duty gearboxes, and solid metal rollers to grip the tyres, they do carry some weight. However, modern engineering has drastically reduced this over the years.

As a general rule, a high-quality single-axle caravan mover will weigh between 30kg and 35kg.

When you consider that a standard user payload on a modern single-axle caravan is often around 150kg to 170kg, a motor mover will consume roughly 20% of your total allowance. For the vast majority of caravanners, sacrificing 35kg of payload is a very small price to pay for the ability to effortlessly pitch their caravan on a 1-in-4 gradient at the push of a button.

Single Axle vs. Twin Axle Mover Weights

The weight of your system will depend entirely on the size of your caravan and the type of mover you require.

Single Axle Movers: Systems designed for single-axle caravans utilize two motors (one for each wheel) and a cross-actuation bar. The Powrtouch Freedom, designed for lighter caravans, weighs approximately 32kg. The heavy-duty Powrtouch Evolution Single weighs approximately 35kg.

Twin Axle Movers (2-Wheel Drive): If you have a twin-axle caravan but only require a standard 2-wheel drive mover system, the weight impact is incredibly similar to a single-axle setup. Because it still only uses two motors, the system weight remains around the 35kg mark.

All-Wheel Drive Movers (AWD): For maximum traction on heavy twin-axle caravans, an All-Wheel Drive system is the ultimate solution. Because an AWD system uses four independent motors to drive all four wheels, you are essentially doubling the hardware. Therefore, an AWD system like the Powrtouch Evolution AWD will add approximately 70kg to your payload. If you are fitting an AWD system, you must calculate your payload carefully.

Factoring in the Leisure Battery

When calculating the weight impact of a motor mover, many people forget to include the power source. A motor mover draws significant current and requires a healthy 12v leisure battery to operate.

If you do not already have a leisure battery fitted to your caravan, you must factor this into your payload calculations:

• Standard Lead-Acid / AGM Batteries: A class A NCC approved reliable 85Ah to 100Ah battery (recommended for motor movers) will weigh between 20kg and 25kg, weights vary between battery manufacturers..
• Lithium (LiFePO4) Batteries: If payload is incredibly tight, you can upgrade to a lithium leisure battery. They are significantly more expensive, but a 100Ah lithium battery is significantly lighter consuming less of your payload.

Combined, a standard single-axle mover (35kg) and a lead-acid battery (25kg) will utilize around 60kg of your overall MTPLM.

Why the Powrtouch Range is Designed for Optimal Weight Distribution

When adding 35kg to your chassis, where that weight is placed matters.

As the UK’s number one caravan mover manufacturer, Powrtouch designs its systems to be mounted securely to the main chassis members, directly adjacent to the axle. By keeping the weight of the motors centrally located, it ensures your caravan’s noseweight is barely affected, maintaining optimal stability and safety while towing at high speeds.

Furthermore, Powrtouch utilizes advanced, lightweight aerospace-grade aluminium for its extrusion rollers and high-strength alloy composites in its casing. This ensures that the Powrtouch Evolution and Powrtouch Freedom deliver industry-leading power and torque without adding unnecessary, dead weight to your chassis.

If you are ready to upgrade your caravan with a system that balances lightweight British engineering with the peace of mind of a 5-year no-quibble guarantee, explore the full Powrtouch range online today.
