Basically
Strip interior components out from the corner you are working on, so seat, trim, everything
Work around removing all 10mm screws and all self tappers, including 3 under plastic trim on b pillar and screws down tailgate aperture
Then starting at the b pillar, pull cut pry the panel off against the sealant, the seam sealer at the top under the gutter needs cutting with a Stanley knife first, and gradually you can yank/work it off, then unhook around the rear corner.
Plenty of effort required but maximum an hour per side really, think my first ever took 2 hours actually.
