This company will never go out of business. If you do a search online for UHAUL, you will stumble across LOADS of, "I hate U-Haul", and "U-Haul Stinks" sites. But those same people who make these sites and rant and rave about their terrible customer service are the same ones calling and visiting at the end of the month looking to rent a truck.
U-Haul has the moving industry on lock down simply because more often than not it's the first name you think of when it comes to DO IT YOURSELF moving.
Although I must say that some of their business practices could use some improvement, (One Way Rental reservations need to be revamped to ensure that every customer who reserves, actually receives the exact equipment they asked for), all in all I think there is no way that this company will ever go bankrupt, or not survive unless the consumers really start sticking to their word when they say they will never use them again.
