"The only trouble I've run into with this setup was that my gate valves froze up once and I couldn't dump. They make gate valve heaters that I may add to fix that."
The issue with dump valves freezing up preventing dumping was a problem I solved by channeling exhaust gas from the tailpipe via a flex line sold at auto supply houses. The original purpose of this hose was to channel dealy gases outside the enclosure that a vehicle was being worked on. I store the hose in a made up cylinder of PVC pipe capped with screwed on plugs and hung it behind the rear bumper. The dicharge end is affixed with a made up wire hanger bent to hold the flex tube so that most if not all the gasses discharge at and around the valve. Really cold freeze up or windy conditions have required as much as 15 minitues the thaw the valve free enough to crack open an allow flow to begin. Needless to say that the discharge hose to the dump openning needs to be in place.
