I could be completely in left field, but I think she lied about who and how the BMW was hooked up, and the person liable turned out to be completely JA [scam]. U-haul had no liability. So then she could have said, sorry but email contract is not valid [scam] and I never even insured the car [scam]. She told Flores via a phone conversation how the check that was found at his house was for $200, two months payment. That means she had not paid May. So she left the check to show she WAS paying for the car, but she in reality had no intention of paying for it.
Does U-haul ever help hook-up a car? Then they would be liable, so I doubt it.
She was overly concerned over the check from the beginning.
This issue would explain the reason for the last argument...."you are a *advertiser censored*, etc.". Travis was in financial trouble and it would have hit him hard to have to continue paying for the BMW loan plus a new car and then the repairs.

U-Haul gives instructions....nothing more that I can find.
ADDED: I think Travis was finally done with Jodi over the BMW and her lying about what happened, and she knew it.
