We are fortunate enough to have our TT parked on our property, so therefore we wash and wax it there.
Just as Grumpy indicated, as to the amount of water needed to wash these TT's, I can't imagine washing it at the CG due to the fact it would make a mess of the immediate grounds surrounding the TT, while camping.
Now, if there was a designated location just for the sole purpose of washing, of course, after packing up and before heading out, that would be perfect if you have time to kill.

The best plans can be of those that happen in the spur of the moment!
