I need to ask a question about chapter 11

i'm in chapter 11 and lost my other business also, so now i,m going to file for chapter 7 because I have eight fraction in my foot and it will take a year to heal. so i,ve been I chapter 11 for a year 1/2 and now the only thing I have left is my truck and because it was part of the deal which was to sell my building which was apprised at 800,000 before the market fall . and the agreement was to sell it but it didnt sell and I didnt make money to pay back any thing. I would really like to keep my truck but usaa want the value of 16,000.00 I payed 6 years and almost had it payed off before everything came to the end. I want to keep my truck is there any way to have usaa come down on the price owed. I really need an answer thanks so much , I a single woman.
