I use SeeLeveL sensors mounted on the outside of our grey, black and fresh water tanks. A little pricey but 100% accurate 100% of the time. It is great to never give tank monitoring another thought - ever. After spending spending nearly 6 figures on a MH, what's another $200 to get something that actually works.
SeeLeveL uses your existing wires and takes about 3 hours for a DIY install.

X2 on the SeeLevel sensors and monitor. Money well spent for my piece of mind. Since the display reads out in percentages (except for the battery level), it's much more accurate than the "Empty, 1/3, 2/3. Full" panels.
It doesn't hurt to travel with 1/3 to 2/3 full, black and grey tanks. The road action will clean off any debris along the sides of the tanks. I do it occasionally and so far I have no problems. In fact, I deliberately do it annually to make sure nothing does build up. This is my 2nd coach, and it worked on both of them. 2 years ago, I traveled across country in 3 days with full tanks to be sure the process works. Good Luck........

Our new to us 06 coach had the 1/3 level lit all of the time on the black tank. I assumed it was crud on the sensors since i didn't know the history of how well the tanks were maintained. I disconnected the wires to the sensor terminals on the black tank and the light was still lit! Long story short, the readout board was bad and there's nothing wrong with the sensors. Not the majority of the failures but thought I'd share it.
A while ago someone mentioned putting a bag of ice in the toilet/black tank to help scrub the tank before taking off for home. Obviously can't be done for the grey unless you took one of the drain screens out in the sinks and dumped it in there. I have been considering a tank wash for both black and grey. Fairly cheap and easy to install and works off the power of the hose. Any thoughts on these? I will say however that I don't ever really have any issues with my tanks. Plenty of water and dump only when full is a process that seems to work. I back flush them once or twice a year with a kit. Cumbersome and the installed tank wash seems to be the same principal but easier.

This is the worst advice I have ever read. The reason is when the gray tank water starts to come up the shower it stinks terrible. Best thing is to solve the problem the right way. Many people are just too tight to use the proper chemicals that will keep the gray and black tanks clean. We use enzyme type solution. An organic substance that is produced in plant and animal cells and causes changes in other substances by catalytic action. We use Happy Camper. It is a bit expensive, but it keeps the sensors clean all the time and when you dump does not smell at all to where sometimes people that do not use anything run the neighbors out of the campground.
Calm down RayChez, this was partly a joke as most everyone's tank sensors don't work properly. I do use chemical in the grey. I do look at the sensors but don't get bent if the black says full when I know it's not. With use you get to know your tanks. I have NEVER had my grey come up the shower in our new TT, the old one on occasion but no big deal

Thanks everyone for your thoughts. I have been sitting awhile, so we'll see what happens after I drive tomorrow. I'll leave some water in the tank to swish around. Don't happen to have baking soda around. Is it okay to put the same chemical I use for the black tank into the gray tank?

Not sure what kind of chemical you use on the black tank. There are some blue stuff that are just for cutting the smell down. What you need is an enzyme type chemical. They sell them at Wal Mart. Drop a couple of tablets into both black and gray tanks and let it set until you are ready to dump again. It will clean out your inside of the tank and sensors.
