Question for truck drivers with a J. B. Hunt lease purchase...?

My husband and I are half way through our lease purchase agreement with J. B. Hunt, and have some concerns. I'm looking for a driver who has completed the process that can answer a question for us. Did you, or did you not have a balloon payment at the end of the 36 months in order to fully own your truck? J. B. Hunt swears up and down that there is no balloon payment, but the language in the contract is tricky. I'm just hoping to hear some firsthand accounts on this so I don't have to pay a lawyer to tell me. Thanks!
