About the Aiways U5 2021 boot

The U5 is one of the more forgiving boots to load. The opening measures 39¾″ wide by 29⅞″ tall, the floor runs 41″ with the seats up, and folding the bench takes it to 73¼″, a gain of 32¼″. Width holds at 40⅛″ at the narrowest point, so the space stays close to square. The sill sits 29⅞″ up with a ¾″ drop to the floor, near enough level to slide heavy boxes straight off the bumper. Long flat cartons suit it once the seats are down. Load those first, then pack around them.

About the FJÄLLBO Shelf unit, black, 20 1/8x53 1/2 " package

FJÄLLBO ships as one flat box, 53″ long by 14¾″ wide and just 3¾″ thick, at 24 lb 4 oz. The length is the only real problem: 53″ rarely clears a trunk opening with the seats up, so plan on folding the rear bench in anything smaller than a wagon. The box itself is a one-person carry, but the slim profile flexes if you hold it by one end; support the middle or carry it on edge. Angle it through the tailgate diagonally, long edge first, and let it lie flat on the folded floor. Check the label against your order before you leave the racking aisle.
