For those of interest, I have a 1977 Kingsley with a full bed in the back. The tank and pump are under the bed. The mattress is next to impossible to remove, especially by yourself. I wanted to set up for quick winterizing using coach pump for pink fluid. I purchased a Camco Permanent Pump Converter Winterizing Kit- Allows You to Use Boat/RV Water Pump to Fill Pipes With Antifreeze - Lead Free, CSA Low Lead Content Certified (36543) from Amazon $14. I located a place in the outside propane area to attach the new valve. I connected 1/2" plastic hose to tank outlet to one side of valve and another from other side of valve to pump. Since the drain is also under the bed, I put a 1/2" barbed tee that had a 1/2" MPT where I can cap it off until I need to drain. That is also in the propane area. There you have it. Obviously, you can use whatever sizes work for you. If you do very cold wx camping, you would need to wrap that in insulation.
UPDATE! The above was written as if I had done the bypass, actually it was THE PLAN. Now for the 'Rest of the Story'. I decided to use Pex and Sharkbite connections. I have included pictures that explain things pretty well. The part that really worked out was the Pex washing machine connection attached to the water hose elbow for putting in the pink anti-freeze.
