Turn in motorhome back to bank

Never did put any numbers on the unit. This is a fact. My friend bought a 2005 DP in 2006 that had 4500mi on it and still had plastic over the carpet for $48,000 from a bank-----the unit had sold for $170,000 new and the original owner got stuck for whatever difference there was......the bank could care less what they get for it. They want it gone and then they come after you adding every fee and expense to what you owe along the way......You need to sell it for whatever you can get and somehow absorb the loss your self. Put some numbers on it here.
