For a lease just make sure that when you sign they dont have some mocked up way of making up price like paint up to par and lift up to par.Get a service contract with who ever you get trucks from and if they are not up to spec tell them well your guys serviced them.Check dealer out and try to stay local that way your not out travel to and from customer.Ask for refrence of who they have serviced and chech with them ,see if they will tell you who they lease to for more than one term.Homework pays off
