How about the theory that cooling hot water freezes quicker than cooling cold water?
That theory has been proven to be bogus.
It is true that hot water initially loses heat faster than cold water, because the rate of heat loss depends on the temperature differential between the water and its surroundings. BUT the hot water still has much more total heat to lose before it gets down to the same temp as its surroundings, so it is less likely than the cold water to freeze in the same amount of time.
I think this is a good simple idea and wouldn't cost much to try out.
The lines & pump will be full of warm water. Plus the warm water in the tank will radiate some heat into the area of the pump uptake line. If you could wrap Reflectix all around the tank & uptake line, that would be helpful. (I'm assuming you are talking about an exterior tank with an uptake line to the pump inside the trailer.)
