You don't need a huge truck to move pallets. A standard Sprinter van can carry three or four and you can get specialized vans that carry six.

There's also a huge space between 18 wheels and Sprinter. Fun fact: There's even cargo bikes that can carry up to 3 euro pallets (though that's clearly stretching the definition of "bike" to the breaking point) https://pulse.dbschenker.com/de/xxl-lastenfahrrad-europalett...
