Heated water hoses, fresh and waste. Whats your solution?

Tell us about your experience with homemade or factory made fresh water hoses.
Of the several mfgr. brands, and homemade ones have they serviced you well or not in extreme cold, at what cost and with what material?
Waste hoses are also even more prone to freeze up, a potentially disastrous problem to the un educated who 'trickle' their fresh water to keep it flowing without considering the much slower flow through the 3" poop pipe. That one has to be heated and insulated even better.
