So the newest mod I am working on is a larger fresh water tank, and the grey water recycling system from USI RV. The stock fresh water tank was 20 gallons, and the grey and black are 30 each. I decided I wanted more fresh water, but with only 30 gallons of grey I either couldn't add too much, or I needed to find a way to move water from grey to black when grey got full first. That's where the grey water recycling comes in. It is a system with valves, check valves, and an extra water pump. It uses the water from the grey tank to flush the toilet, but not before it goes through a big *** filter. I have about 9 hours into it right now and probably an hour left to make it complete. Today I mounted the larger tank, filter, new pump and valve. I just need to wire it up and drill into the grey tank for the feed line. Here are a few pics, I will get more when I am done.

New tank in place, barely fits.
