Has anybody done a camping conversion of the Terracan boot space that they'd be willing to share with me please?

Looking for ideas on how to go about putting in a raised platform that fit over the wheel arches, and space for ammo boxes or sling racks underneath. Likely remove the rear seats for this to make extra length available.

A modular system that is both "solid" and relatively easy to remove and stow would be a winning bonus - the 'Can is my only vehicle (apart from a motorbike) so needs to fill multiple roles.

Alternatively, if there are any reputable companies in the great Cape Town / West Coast area that specialise in such conversions, please point me in the their direction.
