Your two best options are to use a heated hose or insulate and heat your current hose. A heated hose is obviously more convenient but also more expensive. Last I checked a Camco heated hose was around $170 for a 25ft. Where as you could insulate and heat your current hose of the same length for about 1/3rd of that. So, it depends on your budget and level of effort you want to put into it. 🙂
