It's a breeze actually. Remove the front seats, middle seats are a pain they are very heavy if it's a bench, and the 3rd row if you have them. Then remove the center console it has two bolts beneath the radio behind the tray/cig lighter and a bulk wire harness beneath the cup holder. The tabs for it slide under the inside bolts of the front seats.
You don't have to remove any of the pillars but the front kick panels may assist with removal of the front half. Pop out the 4 door sills. For the cargo half you have to remove the star bolts for the cargo hold-downs. Use star impact sockets. Also remove the rear hatch door sill trim it also pops out. The trim that outlines the 3rd row hooks lift out on their own and with the rear carpet. All that is left are the brittle and easily torn insulation.
Remember not to trash it just yet, use it as a template of where to cut access holes for bolts, harnesses, etc

Stripped the old material off of the headliner. Be careful as it can crack easily. Started at one corner and worked gradually left to right and so forth long ways until I was at the middle going downward, flipped it 180°, and started again. Now to order black suede online and get some 3M headliner spray from O'Reillys
