RV Trust, part of the Trust Holdings group, has adopted Carstay's SAny.KIT assembly kit for the interiors of its motorhomes. The kit enables conversion of a Toyota HiAce cargo area into a camper interior with a wood-grain floor, slide-out sofa bed, storage cabinets, and sink in a few hours, meeting requirements for 8-number camper registration. RV Trust used SAny.KIT for its 'Car Camping Camper' model, displayed at the Yokohama Camping Car Show 2026 on September 26–27, reducing production time from three months to about 1.5 months. Carstay will exhibit SAny.KIT at the Japan Mobility Show bizweek 2026 at Makuhari Messe from October 13 to 16, 2026.
