I take a annual trip to Talladega and we have the same set up. Build a wall that you can put between you and you trailer. Make it 2' taller and 3' wider than your generator. Foam will also help. Do not build a cover or box around it!!! We had a some one next to us that had a 2500w covered on 3 sides, ( had about a 12" air gap all around ) woke up in the morning only to find the gas tank had melted down and around the motor and generator!! It had a 5 gallon tank on it. I have a 18hp twin 13,500w that I use for back up at home, 7 gallon tank, when it runs out of gas, the tank is pretty warm, all I use is the wall. You will find you will here your neighbors more than your own.
