also, i do disconnect water hose at night from the motorhome and i dont leave the sewer hose connected like i usually do. and i dont dump till afternoon when things have warmed up. not much if any insulation in the slide out, so your head may get cold at night. i have a separate electric wall mounted heater in bedroom to cut down on gas furnace cycling on and off and i put in a Coleman heat strip in the air conditioner very simple install. about 35.00. it doesn't heat the motorhome. just takes the chill off.
