I put two toilet cutoff valves in mine which I shut when the tanks start to overflow meaning they are full. I leave them this way when going down the road and open them back up when I use the FW tanks. I think they need to be open so that they can equalize pressure when in use.
I wasn't aware that our Eagle TT's have two FW tanks! With the 82 gal. FW capacity, it makes sense, though. Then are these two tubes both overflows, one for each tank? Or is one an overflow and one a vent?
Regardless, I just picked up two 1/2" barbed to 1/2" MPT fittings, a couple of 1/2" - 1" screw-tighten pipe clamps, and two 1/2" FPT x 3/8" straight shut-off valves. Next chance I can, I'll do what you did and take some pics.
