A great mod, I added one to both of our TTs. Nice when you flush in the middle of the night and the pump doesn't come on right away. A "companion mod" is to add flexible supply line between the pump and the pex tubing, it quiets the pump down quite a bit so the pulses of the pump aren't transmitted to the hard lines.
Here is the one I put in the Terry, I got the tank at the home center because it was quite a bit bigger than the RV model. Be sure to buy one that is rated for potable water, some are designed only for use in hydronic heating systems.
Also note that I added a valve to isolate the tank for winterizing purposes so I'm not wasting pink stuff filling the tank.
