We had a continuous installed in our Fuzion because we are full-timing with access to water and sewer so no issues there. When we go “camping” or just living in a campground for a few days it’s not an issue unless we don’t have sewer. If I was just using it for camping trip I would absolutely stay with the regular water heater but ensure it was gas and electric. I always turned on the electric on our old unit once we got setup and never had to worry about hot water. We also had a 10 gallon and that helped too.
Hopefully this will be a non-issue for you once you get to inspect the rig.
