Does anyone have any experience with them ?
Airstream Interstates come from Jackson Center with electric dump valves and macerator pumps. Discharge line from the tank to the pump is still your standard 3-inch line, but the pump discharges through a smaller line (3/4-inch, if memory serves).
I don't know who actually makes the electric dump valves that are installed on the Interstate, but you can't beat them for convenience. The first couple of times I used the electric dump valves, I didn't hold the switch long enough for the valve to open fully; the valve opens slowly. Once I figured that out, I had no trouble ever since. Switches are lighted so you can tell if the valve is open or closed (light on=open, light off=closed).
Only problem you might have is that no matter how conveniently you place the electric dump valve switches, the discharge hose is still down where it's awkward for people with old backs like yours— or old knees like mine— to reach.
I solve that problem by carrying a small folding stool. At the dump station, first I set up the stool, then I sit on it to unreel the hose and operate the dump valve switches.
