Mega Lite Extreme Rv

Are you looking to camp in it or store it? If its below 32° you are going to be at risk for freezing your lines. Take a look under the RV is open (can you see the tanks) or is there a corrugated plastic covering it? If you have the plastic usually the units leak enough heat from the propane furnace to keep the lines from freezing in mild temps. But if you get low they can still freeze. You can look at adding tank heaters, but I doubt that unit came with them originally.

If you are not camping with it in the winter then you need to plan to Winterize it which can be done with the RV antifreeze and/or blowing the lines out and draining the holding tanks, water tank and water heater.
