Mobile Home Community Obligations

[Anna Strong]

Hey there.
I want to know if there are any legal obligations of a mobile home park owner to inform trailer buyers of previously existing lot utility problems.
I bought my trailer already on a lot that apparently had electrical problems at least 3 years before I purchased the trailer (located on the same lot it currently stands). The former owner called out the city (in 1999) who told the then current owner that there were problems with the electrical lines in between the meter and braker exterior to the trailer. I assume the then owner decided not to pay for it because the cost was over $1,000 and she was responsible (by lease) for maintaining the line inbetween the trailer and the meter.
I returned recently after 3 weeks of vacation to find my A/C and refridgerator not working. I found out all of the above subsequent to my return and the park has paid for the work exterior to the trailer but does not feel responsible for anything interior (the electrical problem cost me $425 to replace my A/C compressor). Since it's in my lease that I am responsible for the line inbetween my trailer and the braker, I assume that the park is covering their ass since they neglected to tell me that they were leasing me a lot with a known faulty line. I am not sure. I would like to get refunded for the $425 + spoiled food and the inconvenience of not being able to live in my house because there was no fridge (otherwise 1/4 months rent).
Do you know of any laws binding them to telling me of existing problems on lots and could I get back the money I spent in the house that occured because the lines failed?
Thanks.
