Uphill loading occurs when the truck is parked in the traditional manner with the passenger side to the residence and the truck is sloped from the front to the back. Since the crew will be stacking the furniture in vertical tiers, having the tiers lean backwards because the truck is uphill is dangerous to the crew and to the shipment items. In these cases, the driver will usually opt to park the truck with driver’s side to the residence and the front of the truck facing downhill so gravity is working with the loaders; not against. This is why moving vans have several side doors on each side.
