Mobility Conversion

You won't because all these companies have their own bespoke designs.

There's a hell of a lot of structural work involved in some of them.

Too right.

Mine for EG is taken directly from the factory in Canada to a plant in Michigan where they remove engine exhaust, suspension at both ends, most of the interior, and then they cut out the complete floor from engine to the rear end.

Then they weld in a complete ne bespoke floor, 10 inches lower, rustproof, repaint, and then fit extensions to the sliding doors as well as relocating all the door bottom track and other workings.

Then they refit the inside using bespoke mouldings and carpeting etc. This includes totally rewiring and repipeng most of the van and air con, fuel, cables, exhaust, etc. Then they fit bespoke body mouldings to cover the lowered floor outside. Thats before the thing has ramps, a computer thing in the boot that controls the ramp, door opening, suspension kneeling, etc. It has to not do it in the wrong order, not do it if someone pushes a button while moving (or at the lights!) etc. Thats before you realise theres now no room for a spare or a fuel tank which are also relocated. Trust me they are a production line job with everything having been evolved over many years to work properly and so that over the counter parts like exhausts, looms, body panels, carpets, removable seating mountings and chair tie downs are easily available...

Its no one off custom job.

Have a look at mine.

My sis-in-laws Fiat Doblo is adapted to a similar level.

Yep. Not something you may want to tackle at home because there are no off the shelf mouldings or interior panels and stuff. It would be more expensive than buying one.
