No low point valves, just the caps but they are easy to access and remove.
They all freeze up below 30 though... even with the extreme thermal package and the heat running full time. Apparently heat doesn't make its way around our underbelly too well.

WOW, do you know where the system actually becomes frozen? I assume you are using the 12V pump when temps drop below freezing. If so, the most vunerable part of the system should be the pick-up tube. If the tank is full, it will take quite some time for it to freeze. And the pump should stay warmer than the pick-up tube. If the tank is at the rear of the trailer and the pump is located further forward, then the long water line may be too exposed.
On my existing brand, I have camped at temps below 20 degrees for several days and never had anything in the trailer freeze. And that is with the furnace shut off, just using portable electric heaters to keep the unit warm.
