Voyager is Feeling Gray Today

As you may have read in an earlier post, "Monitoring The Poop", Voyager has a 45-gallon gray tank.  In our situation, gray water storage is the most useful in many types of campgrounds were we will stay, so any increase in gray obviously means more freedom.  This modification is completely dreamed up by me.  Most of the time with a modification, I get an idea from someone else.  With this one, I've not read of anyone doing anything close.  In the pics below, you'll see where I installed two shut-of valves which control which way the water flows--either directly into the under-the-trailer 45-gallon tank or to the 65-gallon additional in-bay tank I installed.  If you look closely, you'll see from the pics that once the new 65-gallon tank is full, it begins to drain out.  What you can't see behind the wall is that the pipe routes through a p-trap and back into the under-the-trailer 45-gallon tank.  Combined, I now have roughly 110 gallons of gray water storage if needed.  Or, if chosen, the tank and pipes are designed to pull out and have full use of the storage bay.  Google p-trap if you want a pic of it.  Basically, it is designed to contain a small amount of water which prevents gas from coming back up and stinking up the place.  All home plumbing have p-traps.  The front of the new tank has a faucet on it where I can attach it to a hose and using my macerator pump (black plastic box next to faucet), drain it.  The tank is held into place with two ratchet straps.  Here's what it looks like:
