That’s a good point. There is a type of delivery in the US that’s all-inclusive, where more than one delivery person show up and it’s assumed they bring it in and install it.

Standard delivery though is often some form of freight where final delivery is handled by a local carrier/vendor. Usually they arrive with a commercial delivery truck rather than a van or pantechnicon.

Unloading from the trailer to a loading dock is the easiest. Curb delivery is possible if the trailer is outfitted with a lift or a slide out ramp. But any further and the delivery can become a lot more involved, enough to throw off their delivery schedule.

Drivers often still offer to do it unofficially as a side-hustle, but if I don’t have cash on hand I won’t ask them to do it just as a favor.
