TowBox V3 towball-mounted 400L luggage box, black, TV3XNN0

RRP: £1100.00

A top quality, stylish and aerodynamic rear luggage box that not only tilts, but slides away from the boot to allow for easy boot access. The TowBox V3 is bulky to move about, so use the built-in trolley-style wheels to move it, loaded or empty, from its storage location to the vehicle tow ball.

See important notes in the Description tab.

There has long been a market for carrying luggage boxes behind vehicles rather than on the roof, mainly for ease of access. Most of these rear boxes are quite basic, and are usually fixed to separate platforms or onto tow bar mounted bike carriers.

Only one brand that we know of has really given this sector the attention it deserves, TowBox, a brand created and developed over more than 15 years by Spain’s premier designer and manufacturer of towbar systems, Enganches Aragón.

They have created a range of rear boxes that are strong, secure, and water-resistant to IP44. TowBox V3 can not only be tilted, via a control handle on the outer edge of the box, but it slides away from the rear of the vehicle before tilting, to allow easy access to the boot space - this is a really useful feature (unfortunately it won't tilt far enough to allow most vertical tailgates to open - see the specifications tab for more details). To keep the centre of gravity as close to the vehicle as possible, and to allow for maximum loading, the TowBox V3 slides over the tow ball coupling system before driving, another very neat solution.

TowBox V3 also has a 2nd mounting position, which gives a bigger gap between the box and the back of the vehicle. This feature allows the TowBox V3 to be used on vehicles with a spare wheel (the maximum load is reduced to between 30 - 40kg if you have to slide it out to accommodate the spare wheel).

TowBox V3 are very stylish, with really smart five-function LED lights, and have been designed with efficient aerodynamics in mind.

They even have trolley-style wheels, allowing the box, empty or loaded, to be wheeled from your base and placed onto the towball.

Rear-mounted boxes produce less drag than roof-mounted boxes, and are generally a better solution for electric vehicles. There’s no doubt that, all other things being equal (vehicle load weight, driving style and speed, and wind speed) a 400 litre roof box will use more of the vehicle's energy than a 400 litre box mounted behind the vehicle, although on the downside a rear mounted box will of course impose many more limitations on shape and size than a roof box, or an open roof rack. Additional drag is of particular importance for electric cars because the extra energy used will reduce the range available before recharging is necessary – fossil-fuelled vehicles usually have a longer range, can refuel much more quickly, and can carry their own extra fuel if necessary.

  • Internal measurements: 119cm wide x 60cm deep x 58cm high
  • Empty weight: 38kg
  • Maximum payload: 50kg (tow bar nose weight limit permitting)
  • Capacity: 400 litres

  • The TowBox comes with two locks; one for the tow ball and one for the actual TowBox
  • TowBox V3 may be fitted to vehicles with rear spare wheels
  • A 13 to 7 pin adapter is included, allowing the TowBox V3 to be used on electrical systems with 7 pin sockets; note that the reversing light will not work unless a 13 pin socket is fitted, and probably not the fog light either - this depends on the details of your vehicle's tow bar wiring
  • TowBox are water-resistant, tested to IP44 ('Protection against splash water from all directions'), the standard applied to all the rear boxes that we are aware of. Any rear box is particularly vulnerable to high pressure road spray, so please pack any vulnerable belongings in waterproof containers

TowBox are manufactured in Zaragoza (Saragossa) in Spain's Aragon region by Enganches Aragón, an ISO 9001:2015 company that is now over 30 years old, and is a major European manufacturer of tow bar systems. The first TowBox entered the market in 2009, with the V3 launched in 2019 - all models have been refined over time.

We are aware that there are web shops based in the EU who are offering to sell TowBox V3 to UK customers at prices that look much cheaper than our pricing. Just be aware that their prices probably do not include the UK's 20% VAT (VAT is payable on imports over £135) and also the customs clearance charges that the courier will make.

To give you an idea of the likely VAT cost, a product shipped in from the EU with a price of £850 and a £50 freight cost, so a total £900, would have VAT to pay before delivery of £180.

*The TowBox V3 slides and tilts to allow a standard tailgate to open. It doesn't usually give enough space to open a vertical tailgate (you cannot open a Transporter tailgate with a TowBox V3 fitted). This diagram shows you how far the TowBox V3 tilts away from the tow ball.

Delivery FAQs

When will my order arrive?
There are no deliveries on Saturdays, Sundays or Bank Holidays, except for postable items where Royal Mail has a Saturday delivery. Express Delivery orders placed on a Friday (before 1pm) should be delivered on the Monday or Tuesday, Express Delivery orders placed on a Saturday or Sunday should be delivered on the Tuesday or Wednesday. The arrangements for Very Heavy Items are different and are shown above.

What about Next Working Day delivery?
We have offered a reliable Next Working Day service for well over 20 years but, due to the pressure on the couriers caused by the coronavirus crisis and the huge increase in online shopping, we can no longer be confident about the delivery date, which is why we now call the service ‘Express delivery’. Most Express delivery orders will arrive on the next or second working day, but some will arrive on the second or third working day, or be split between these days. So-called “split deliveries” happen when the couriers do not have enough trailer space for everything that should be moved around the UK, so they will load what they can and leave the rest for the next trailer.

Is my delivery day guaranteed?
No retailer or courier company can ever "guarantee" a Next Working Day delivery. As well as split deliveries, all courier companies occasionally have the same transport problems as can happen to everyone else, including snow blocked roads, closed roads, traffic jams, mechanical breakdown, an inability to find the delivery address, or to gain access to it if, for example, it's in a block of flats. We work with some of the best couriers in the business, and overall they provide an outstanding service.

Do I need to be at home?
We are very flexible with our deliveries and will aim to deliver to an address which suits you – this does not need to be your home address. Goods can usually be left without signature - we prefer this with roof boxes. There's a "Special Delivery Instructions" box in the checkout area where we'll ask you to choose a typical instruction and then amend it to suit your particular requirements.
