Hand-picked for this exact result — no generic lists.
Load it like a mover.
Volume is only half the story — the rear door decides what actually goes in.
- Measure the rear door.
A box that fits the volume may not pass the opening.
- Count on 80% efficiency.
Furniture, mattresses and soft items never tile perfectly.
- Heavy boxes low and forward.
Weight over the axles keeps the truck stable.
- Strap every tier.
A tier that shifts in transit crushes everything below it.
