If you watch the forecast and do a little advance planning cold weather won't be a problem. We stopped in Carlsbad New Mexico last month on our annual trek to southern California. it got down to 22F overnight for a couple of nights with some wind, at those temps the hose would have froze. Previous experiences with frozen hoses (and damaged pressure regulators and gauges)has taught me to put water in the tank and run off the tank overnight. The furnace keeps all the pipes warm and I re-connect in the hose in the morning, if necessary I repeat the process the next day. Trying to stow a frozen hose for travel is no fun!
