You do the same work in both scenarios but the power exerted is different. Since on a ramp the work is done over a longer distance the force you have to exert is decreased. Therefore, it "seems" to be easier to push a box up a ramp rather than lift it up.
The load in a full truck is mainly higher than the centre of gravity (COG) of the empty truck. As a result the COG of a full truck is higher. It is this than makes it easier to tip.

A pallet truck is a manually-operated device for lifting and moving pallets.
inclined planes
The force required to pull a truck up an inclined plane depends on the weight of the truck and the steepness of the incline. The force needed would be higher on steeper inclines and with heavier trucks. This force can be calculated using the equation: Force = Weight * sin(angle) + frictional force.

You help a buddy move, and he rents a moving truck. To load or unload the truck, you take the ramp out, attach it to the rear of the truck and let it slope to the ground. The ramp is an inclined plane.
