Stupid Question - negotiating purchase of surrendured secured collateral

[debtinohio]

Ok - some may have read my thread where I was forced to surrender my RV since the trustees objection was sustained.

Is it legal to attempt to purchase this item from the bank for a settled amount in cash < than what I owe? Or am I prevented from doing this? I have the cash to purchase it and can explain where I got the cash (we keep tax returns).

Ironically the banks loan is being handled by an attorney in my neighborhood whom I've retained for other unrelated issues in the past.

Thanks!
