Because a plumber needs to carry heavy things, such as a water heater tank, and possibly more as he will intervene on multiple places during his day? And that he may need to get back to the shop/depot in the suburb during the day to get additional parts, if needed? Do you live in a magical word where things teleport by themselves?
I've never worked with a plumber that has anything they need in their van / truck. They always need to go buy something. This departure generally doubles the cost of whatever plumbing is happening.
