Hi Everyone!
I have a complete newbie question: I have a 2024 tab 400 and I want to fill the fresh water tank for boondocking, how do I know when it's full? Is there a way to know besides running inside to check the gauge? Currently I'm running back and forth and this seems silly. Surly there's a way to know when it's full from outside the Tab 400, right?
Also... what happens if I overfill the tank? Will I burst the tank? Will it hurt the fixtures?
Thanks in advance!!

Now, as for overfilling the tank, there's an overflow drain that will start dumping water if you reach the limit. The one thing I've read some people can run into is if insects nest in the drain tube, THEN you can overfill the tank causing damage to the camper.

As @Jay_and_Kat mentioned, when the tank overflows, water will exit through the overflow vent. However, you can also monitor the level of water in the tank using the tank monitor inside the trailer. BUT, keep in mind that the monitor sensors attached to the tank are not always accurate. My best advice is to not leave the water hose while filling the fresh water tank. You want to monitor it for any problems during the filling process. It is unlikely that you will have issues filling the tank, but better safe than sorry.
Another option you might consider is something I just ordered. It is inexpensive, so I want to give it a try and see how accurate it is. If you boy one, however, test it out (e.g., by filling a bucket of water) to see how accurate it is. There are many versions available, but I opted to purchase this one:

After the fresh tank if full I switch over to city water and fill the lines and the Alde tank so I don't waste water out of my fresh tank to do so when I get to camp. The final step is to turn it back to dry camping mode, turn on the water pump and let a little water out of each fixture just to make sure the pump is primed.
