2020 version of a classic Hymer RV : the B704 SL

This van costs well over EUR135k but it is a Hymer and it is a classic - even if it is the brand new layout!

Hymer launched its new generation of its B-Class at Caravan Salon in Dusseldorf in 2017 and here we see the 2020 version.

The Hymermobil B-Class SupremeLine uses the specially developed SLC chassis for this vehicle featuring a high double floor. Thanks to its low dead weight, it has a large payload and the vehicle has a lower centre of gravity aimed at improving handling. It also has independent wheel suspension and a very light weight.

“There was a particular focus on lightweight construction when the Hymermobil B-SL was being designed. We want to offer our customers the highest possible payload reserves in the 4.5-ton class as well. This is something we’ve achieved once again this time around thanks to our advanced technologies, such as the new chassis and the Woodwelding® method. Measuring 7.79 metres in length, the new B-SL 704 for example boasts a mass in running order of just 3,390 kg, which means the payload reserves total an impressive 1,110 kg,” explains Jochen Hein, Managing Director of Hymer.

The chassis also has a low centre of gravity and a large double floor, which doesn’t have an impact on either the overall height or the headroom inside the vehicle. Similar to a basement, all the technical components are completely hidden in the double floor: plumbing and wiring, tanks, all the electronics iand even the heater. Completely closed off and with a smooth surface, the new undercarriage increases the clearance, which significantly improves the aerodynamics, insulation and soundproofing. The double floor in the new Hymermobil B-SL features a spacious through-loading compartment, which stretches across the entire width of the vehicle, can be loaded from outside and is also accessible from inside through a cellar compartment. In total, this creates up to 998 litres of storage space.


The body uses PUAL technology. The roof can also be fitted with an extra GRP layer, ensuring absolute hail resistance.

The Hymermobil B-SL has a panoramic windscreen provides all-round visibility at the wheel. ESP including Traction+ helps the driver on difficult terrain and keeps the B-Class firmly on the road. Thanks to the independent wheel suspension of the new chassis and the lower centre of gravity, the Hymermobil B-SL grips the road well and has good cornering ability.


The characteristic Hymer headlights in combination with the distinctive radiator grille and chrome trim ensure a unique design. The familiar LED hybrid rear lights with the integrated Hymer logo are further accentuated by stylish chrome highlights. The interior of the B-SL is characterised by the ergonomic design of the living area, which offers plenty of freedom of movement, as well as comfort and convenience.

There’s a choice of two furniture finishes: Velvet Ash and Grand Oak. While the light colour Grand Oak combined with the white overhead lockers provides the vehicle with a modern look, the dark wood finish Velvet Ash with its fine grain and soft matt look gives the new B-SL an elegant appearance – the tables and counters with the Oriental surface finish are visually reminiscent of precious marble and also provide the living area with an exclusive atmosphere.

The TV compartment is integrated in the backrest of the seating area, enabling a 32" television to be raised electrically and hidden once again, so that the area between the living area and kitchen looks even more open and spacious. The standard LED ambient lighting concept suffuses the vehicle with a pleasantly warm light. The rear wall, upholstered in stylish imitation leather, always looks its best thanks to the indirect lighting. The rear wall, upholstered in stylish imitation leather, also looks its best at all times thanks to the indirect lighting. The bed has a sprung mattress and 7-zone cold foam mattress.
