Today was a good day - I got under the coach in the back (with two 20 ton jacks). First was to orient the tanks and make sure the drains work.
As was said, the front two tanks are big tanks in line with the frame and the other two are smaller and farther back centered between the frame.
All told there was less than a half teaspoon from all four - only two drained. The front passenger side (black water with oil, enough to get both hands black) and the rear tank more water but still not much.
As the temperature has risen the 'add on' pancake compressor runs less than 30 seconds, generally 25 to 30 minutes - and that is with the Valid manifold still leaking. I have the new aluminum manifold - still need a few more pieces and parts...
