Is it worth leasing a truck to be an O/O?

To clarify, I'm not talking about a company sponsored lease or L/P program (I've read about enough of those one sided deals) I'm talking about leasing a truck myself, directly from say Penske, Ryder or something like it. My reasoning is I'd like to work for myself as I did for many years prior to switching to driving. I'm not new to being self employed, or the headaches that can go along with it BUT I'm seeing opportunity's for O/O's which seem (at least at face value for now) to be something I'd like to get into. My credit should allow me to purchase a descent used truck but I was thinking about leasing for a few reasons mainly that I'd have their maintenance during the lease (that's a huge one) that it would be newer and possibly more reliable than what I'd buy, and mainly to test the waters without committing permanently to a truck just yet. If everything worked out as planned I would definitely want to purchase a truck and not lease but was thinking this may be a smart way until I felt secure enough to do an outright purchase.
