Average Monthly Cost-Electricity When Snowbirding Nov-March

We have a park model that is heated electrically. We have an electric clothes dryer, which my wife uses once a day. This winter has been very nice temp wise in the RGV and we have used the air conditioner quite often in the afternoon. Our electric bill has averaged $45.00/mo for January and February and since I own my lot I pay $9.00/mo meter fee. Most of the RV owners are paying less than $30.00 per month for electric. Plenty of places to get propane for less than $20.00.
