i recently researched trailers... through uhual, getting a in town move, is actually cheaper than gettign a one way move.....
uhual was actually cheaper than the other local firms, where i live.
as far as the company that only rents to a business, got any friends that own their own business? i do....
the tow rig i used for my truck, belongs to a friend of mine, its his work truck, he owns his own roofing company....
but don't forget to mention the issues of what uhaul will or won't let you tow with their equipment, and what you have to tow with
