Working on it...
First thing I did was get rid of the "sewer hose carrier", next I put on a cap with the gray water drain cap on it. I currently use a Sewer Solution
for emptying my tanks.
My game plan is to replace the two main gray valves and the black tank valves with Barker Auto-Drains
(I don't like or trust cable operated). I prefer Barker over other brands because they are made in the USA and they have repair parts available. The new valves will also mean re-plumbing the drain lines to raise them up a bit and reduce the total footage. I also want to put a macerator
on the black tank at the same time for emptying. I have a whole mod thread going in the Coachmen motohome sub-forum
