Is there another way to check the tanks? That's already been answered: look down the toilet for the black and wait for the grey tank to back up in the shower. Perhaps better, if you're using water out of the fresh water tank, when it gets empty and you need to fill it up, drain the black and grey tanks. There is no way either one could be full, although the grey tank will be fairly close.
If you're on city water but don't have sewer hook ups, just learn about how long you can go without filling the grey tank. I have a hard time making it a week. Otherwise, watch the shower basin. Tip: if the grey tank starts backing up into the shower, you can drain a few gallons and dump it down the toilet. That will help flush the black tank as well as get the water out of the shower basin.
