I see its only going down to high 20's in your area. With the heat on in the RV, you should be fine. Welcome to the forum. Depending on how you plan to use your RV over winter months, you will need to search "threads" and make a plan to fit your need. Winterizing has VERY recently been thorougly discussed.
Mine is fully winterized. I plan on coming through west Texas late January on our way to Scottsdale for 2 months. I keep a few gallons of pink RV anti frz with us and have a feeder valve I hooked to my water pump. Took me 20 minutes to install. I can drain my hot water heater and water lines and have pink throughout in 30 minutes or less. For quick overnights traveling in sub freezing temps, we use campground facilities for bathing and use bottled water. Small quantities of hot water can be made on the stove top or micro.
Really it's all about finding your use and ensuring when that RV is "stone cold",
it is winter prepped.
Have fun and enjoy. Life is good
