Spent my first few cold nights in Savannah. I have no trouble sleeping but the ceramic heater I bought for the rig does not seem to do much. Runs full bore all night but still does not get the temp in the cabin above 60. I am worried about when the outside temp gets below freezing. Dont want to run the gas heat in the rig, which works great, because it will run thru it pretty quick. Any suggestions on types of heaters? Anyone use convection types that look like big screen TVs? Does anyone know if services exist to deliver gas to your rig and fill the tank? If I dont fix this then my wife wont come to visit till summer and I need her a lot more than that! Thnaks for the help in advance.
