Wouldn't you be contaminating your grey tank with poop? If you're a person who dumps grey water on the ground at times then you'd also be dumping fecal matter. I wouldn't want to park in the spot after you leave. What if your grey tank would back up into your shower? Not a good practice, in my opinion.
If you have so much more room in the black tank, dump your dishpan in the toilet or put a bucket in the shower and capture your shower water to dump in the toilet.
I have never, nor plan to, dump my tanks on the ground. Actually I've never heard of this practice. As far as it backing up, I keep a pretty good eye on my tank levels and would obviously dump before that happened.
