As we get closer to Fall, a number of Northern Lite owners begin to think about winterizing their truck campers. Even though Northern Lite builds true 4-season truck campers, if you live in areas that see freezing temperatures, you still need to properly winterize your camper to keep it in good condition. It’s never a good experience to begin getting your camper ready in the spring for your first camping trip of the season only to discover that your hot water tank and various houses have ruptured!

In order to help you with your winterization process, we have put together the following guide. If you would prefer to not winterize your camper yourself, then please visit our dealer page to find a dealer near you who can winterize and service your camper for you.
