As long as you pay for it for whatever your getting it for.
It's just here in town
For cross country trips its 5 days !!
Uhauls service is set up to allow you to use the truck for as long as you need. But there is a daily charge For everyday you keep it past 8 or maybe 9 o'clock. I will say you best thing is to call or go to the rental place and talk to the people who work there as they are very good at explaining everything.
