Double cab pickup - removal of rear panel

[KAgantua]

I want to camp in the rear of a double cab pickup with hardtop

But bed length is limited in these cars about 1500 ish.
Ideally want another 20 to 30cm

Is it possible to remove the whole rear panel below the rear window?
Any pickup let's you do that?
