Administrative specialist Suzuki described the conversion of a 2019 Toyota HiAce TRH214 from category 3 to category 8 (camper registration). The owner installed a shower in the cabin to rinse off salt after water sports. According to the specialist, registration was completed without difficulty because the interior equipment met the required standards and a preliminary check had been carried out thoroughly. Compliance is determined by the cabin fittings rather than exterior appearance, and checks are recommended before equipment is installed.
