Spray on foam insulation for exposed dump lines?
Might that help keep things from freezing? With or with out a heated line inside it? Might it be a bad Ideal to run an electric heat line inside that? Is it flammable?

Wrap the pipe in saran wrapm cloth or other non-sticky, THEN apply spray foam. If you want the heat tape, lay that down before the saran wrap. The spray foam is immune to weather and road conditions and the wrap allows for the foam to be removed just like a cast on an arm or leg.
