Yes, you can travel with fresh water in your motorhome tank. In fact, it is recommended that you travel with a full or nearly full tank of fresh water, especially if you will be camping in an area without a water hookup.
However, it is important to take some precautions when traveling with fresh water in your motorhome tank. Make sure that the tank is securely fastened and that the water level is not so high that it could slosh out while you are driving. Additionally, be mindful of the weight of the water in your tank, as it can add significant weight to your motorhome and affect its handling and fuel efficiency.
Before setting out on your journey, it is also a good idea to check the condition of your motorhome’s water tank and make sure it is free from leaks or cracks. Finally, it is important to use only potable water in your motorhome tank, as non-potable water could contain harmful contaminants that could make you sick.
