1. The outlet you are using is on with the lighting circuit. You can verify this by flipping your breakers off and seeing what they control. If this is true then you need to separate the circuits or use another outlet.
2. Your main service is underated for the appliances that you have in your home. This could be a problem in your mobile home, or with the trailer park. Check with your neighbors to see if they are experiencing the same problems. If not then your main service needs upgrading.
Both of the above are dependent on your home being wired correctly.
