Yeah, 50 miles isn't too short at all, in fact, it's kind of courageous!  

We have had the same problem with our sensor for the gray water tank.  It's important to make sure you are level side to side, as that might cause false full readings of the gray water tank.  Using the baking soda (something I haven't done yet) sounds really smart.  As long as you're using water sparingly, you could easily have your gray water tank last as long as the black water tank, which in our case is about two days (lots of folks in here are tougher and better at this conservation thing than we are).  Things like putting hot water on a sponge with dish soap to wash dishes saves water, and when I take a shower, I probably turn the water off and on three or more times, since I soap up with the water off -- same thing for shaving.  I've found that when Ellen washed her hair, the tank really fills up, but then again, she at least has hair to wash, unlike her receding hairline husband.
