Replacing a Atwood power center, recommendations

Thank you Enblethen. There is no other visible damage. I thought about trying to repair it but I am worried about what caused it to begin with. The MH sat unused for around four years. I had to purchase it from my fathers estate so it would not get repossessed and auctioned to satisfy his loan remainder. I have already spent around 4 thousand dollars having everything checked out and repaired by the dealer he purchased it from. I need to get it fixed as soon as possible so I can put it up for sale.
