As I've gotten older I've had to had to work smarter instead of harder. When it comes to transferring water to my TT I use 6 gal green water jugs from Walmart. I set the full jug on the top of the side of my TV bed, put one of a water hose in the jug, and the other end in the fresh water inlet of my TT and let siphon/gravity do the rest. I know everyone's setup is different but this works for me.
