Just for funzies, do a standard Google search on "uhaul". There is page after page after page of testimonials all blasting use of the company for various reasons, and I think I saw one in there written by an employee blasting the company for mistreatment. You don't even have to click on any of the links. The little summaries that pop up should be enough to convince you.
It convinced me.
Makes you wonder if U-Haul ever Google searches themselves???
