Welcome to our nice weather! Where are you staying near Mancos? We have good friends there and go to the Absolute Bakery all the time. We spent last night with friends in Pagosa and they actually had a little snow on the ground. It sounds like your heater is working...just “freight train” noisy? No water running could easily be not enough in the tank...our 2014/15 model has the 5gal tank inside and under the sink; if yours is newer you might have the 11gal tank outside and therefore more vulnerable to freezing. With the warm daytime temps here, I’d suggest winterizing...drain the lines and push some pink stuff into them (and drink the vodka...!). You can run the Alde for heat on propane or electric without water in the lines. Hope this helps and happy trails!
