The only person who can approve or decline you is a lender after a full application as been made. The general rule for mortgage financing is 24 months after discharge with reestablished credit. Mobile homes tend to be a separate category however. In most cases they required a larger down payment and higher rates than conventional homes.
Bottom line is call some local lenders and start by asking if they have mobile home loans. If yes, explain your BK and ask if you could qualify now, or if you'll need to wait. Once you have a couple lenders who have mobile home financing available, you'll know what you need.
