ELI5: How does U-Haul get away with having all vehicles licensed in 1 state?

All U-Haul vehicles I've seen are licensed in Arizona. How can they operate in so many jurisdictions but only pay for licensing in 1 state?

There are laws pertaining to fleet vehicles - in other words, a fleet of vehicles all owned and operated by one company - that allow the company to title and license all their vehicles in the place where the company's main center of operations is located. Companies use this because it allows them to set up a single account under which all the fleet vehicles' tags are renewed at once, rather than being sprinkled on different due dates throughout the year.

In U-Haul's case, their HQ is in Phoenix, AZ, so AZ fleet licensing laws allow them to title and license all their vehicles in that county. Every state has slightly different requirements for how many vehicles constitute a fleet and how fleet licensing is handled. AZ and IL are two of the more common states you'll see on big trucking fleets because they have the business-friendliest fleet licensing laws.
