Heated fresh water hose

Thanks TechWriter for the responses. There is one in use in RV park where I store our MH and I talked to the owner and he has had his for 3 years and very pleased with it, but he did say his brother bought one at the same time also and is on his 3rd one. Go figure. I don't currently camp in winter but have been thinking about going winter steelhead fishing over in N Calif. and will have to do something if I go in my MH. Thanks again.
