It has nothing to do with the size of the US. You don’t drive from NYC to LA to pick up a fridge. You drive to the nearest city. So why should they not be able to deliver it to you?
And if you live so rural that that’s not feasible – well that’s your issue then, nobody’s forcing you to live in bumfucknowhere.
Even if it’s not included (usually for heavy things you need to pay extra) it’s so cheap that it’s below my hourly rate, and you’ll get it delivered to your flat. Makes zero sense to own a transport.
You rent a van like every normal person on this planet.
You can haul pipes on a van. Plumbers in Europe carry them on their roof. You can also leave the rear door open if it’s just once in a while.
You can haul dirty stuff in there, it’s not like they’re lined with fur and suede. There’s also open vans. Notice the low and accessible flatbed where all sides can be fold down: https://rjclowloaders.co.uk/product/open-back-van/
And re the pizza oven, that’s not a theoretical idea: https://azurebikes.com/shop/wood-fired-pizza-truck-for-mobile-catering/
Look at you, trying to be smart!
You don’t need a driving license to drive a pick up in the US? 🤡
