Can I travel with a full water tank? November 20, 2024 at 1:05 pm #42152 IA_CamperParticipant Joined: Jan 2024 Posts: 215 Likes: 234 LikeUp1:: Absolutely. I have always filled it up before leaving. I stock the fridge, stock the RV with all the supplies we need, and fill the freshwater tank full. Never had an issue.
