you obviously haven't thought this thru. Unless your intending on investing several hundred thousand, and already have an entity in mind that intends to lease them from you. I'm sure you haven't considered the federal licensing and certifications, liabilities, bonding,maintenance.Not to mention logistics,line fees,siding fees, huge medieval-aggressive competitors. Most large freight companies, shipping companies, power houses, factories, etc. own their own.
My impression is that you've got the same notion that someone else put to use 200 years ago.
