Our GRP Manufacturing Case Studies

The campervan conversion specialists met with several manufacturers before working with MPM. Jerba Campervans approached MPM in 2017 to have more control over their design and supply chain, making their elevated roofs for the T5 and T6 VW campervans and the new Ford Transit in 2025. Jerba Campervans began converting vans in 2005, they now specialise in converting VW Transporter T6s and are official partners of Volkswagen as registered vehicle bodybuilders for their Transporter T6 and VW T6 camper.

THE CHALLENGE

Design control and supply chain

THE VALUE WE ADDED

Developed bespoke, market-leading roof design. Ensured faster installation with precision

THE BENEFIT TO THE CUSTOMER

Support to create a tailored solution and reliable, repeatable, high-quality production

“MPM are easy to work with, they listen and are helpful, but at the same time are really easy-going in an informal manner.”

Simon Poole,
Chairman, JERBA CAMPERVANS

With the retirement of the VW T5 and T6, Jerba approached MPM to design, develop, and produce a new bespoke roof assembly kit. This new kit for the transit's pop-top roof can be manufactured using RTM, allowing MPM to manufacture the product in higher volumes compared to earlier hand-lay versions. In collaboration with Ford, MPM and Jerba secured design approval in late 2024, ensuring the vehicle's critical safety features remained effective after installing the cassette roof assembly.

Using the latest CAD software and data directly from Ford, MPM created a product designed to mate perfectly with the bodywork of the Transit. Using RTM, the product can be lowered as a cassette onto the van roof and mounted in minutes, not hours, thanks to the dual A-face production process.

The parts are laid as dry fibre and injected under vacuum, using industry-standard injection equipment, providing repeatable quality at speed. Parts can be manufactured rapidly, releasing the tool for manufacture with multiple cycles per day possible from a single toolset. MPM and Jerba Campervans have been working together for 7 years now, and Simon says:

“One of the reasons why we chose MPM was because they were easy to communicate with and they were always there on the other end of the phone if we needed them. We are treated as both an individual and as a valued customer with great personal communication and MPM always delivers us the best possible solution.”
