Potential Modification to relocate your between tires galley valve...
1. Make sure your tank is empty...very important!
2. Pull two of the rear belly pans down.
3. Remove the current valve...
4. Install the Valterra "cable actuated" valve...
5. Route the cable towards rear end of main slide.
6. Drill new hole for new location of handle...
**I had intended to put it forward of tires but belly pans in that area would have to be cut due to all the stuff going through them...so...I opt'd to just settle for a leisure walk to the back for galley draining...
7. Life is now good...well least I'm not crawling to open/close my galley drain. :>
