Rick,
I think I have the same sensor problem, sensors are reading 2\3 full after draining the tank. My concern is that it doen't take much water (MAYBE 2-3 GALLONS) and then the gauge reads full. Next time I take it out maybe the ice & chemical will clean everything out.
After taking the panels off, I found that the clear tank is the fresh water tank and assumed that it's a perfect rectangle. The other black & grey tanks looks like the top portion is flat across the coach but the bottom part is an unknown configuration. Would GS tell me who made the tanks?
Being a first time RV owner is exciting and perplexing to say the least.
I really appreciate your help and that goes for you too Bob.
