I used the power wand method of cleaning the tank. The gauges are still off but the smell when flushing is gone. When I dump later this week I'll flush the tank with the wand again.
Thanks all for your great input.

I'm sure going to have to use my homemade wand to flush our black tank when we get the MH back from the body shop. Its been there since April and the black tank was approx. 1/8 full then. I suspect all the water has long since evaporated, leaving_uh.
