Very much depends on what you use your van for. Bott offers individual modules - with drawers, load cases and cupboards - while Bri-Stor provides a full bespoke van conversion service, which will match the van to your work needs. If you just want a protective covering for the load area then Bri-Stor might be your best bet, as they also offer a spray lining service that covers the load area with a tough, waterproof resin that should last longer than a traditional plywood lining.
