My 2017 Ford Transit SMB came with a mast table and tripod folding base. The tripod was too wide for the aisle. I had a machine shop fabricate a steel plate and back. The Lagun mount attaches to the plate with bolts that go through the mount, the steel plate, the plywood, the seat base the back plate. Works great and is very stable and shouldn't pull through or torque on the seat base. I will post photos once I remember/figure out how.
