About the VW T-Roc 2023 boot
Inside, the T-Roc's boot is 33⅞″ tall from its floor, but a tall box has to pass a lower way in: a gap of 25¼″ above the loading sill. That is because the floor sits 8⅝″ below the sill, which itself is 30⅜″ off the ground. The tailgate opens 44½″ wide and the floor is 39¾″ at its narrowest. Length is 30¾″ with the rear seats up. Folding them adds 27½″, for 58¼″. Some boxes longer than 30¾″ still fit with the seats up, at an angle and on their side. Keep a hand under a heavy box as it goes over the sill, so it does not drop the 8⅝″ to the floor.
About the BILLY Bookcase, oak effect, 31 1/2x11x79 1/2″ package
Heavy and long is a hard mix, and the oak effect BILLY box is both: 81¼″ × 11¾″ × 5″, at 87 lb 5 oz. It is narrow, but that is far too much weight over that length for one person. Placed straight, the box spans 81¼″ of boot floor. Plan the lift before you make it: who takes which end, which way you walk, and where the box goes down. With 87 lb 5 oz between you, neither of you should have to change grip halfway.
