I have had my pipes freeze on at least a couple occasion from the heat not being on, too low of a setting or failure. All great advice here, one other thing I had done on my coaches is installing insulation foam over the pipes. If you have copper pipes which a lot of the older coaches seem to have, I would recommend heat tape prior to adding a quality foam pipe wrap. I would not use heat tape on PVC or plastic pipes. I have used the hair dryer and it will eventually get the job done, getting things heated back up is definitely the trick. I disconnected my pump and took it inside to thaw while I worked on the pipes. I had a pump strainer crack the second time around and replaced it.

I concur with Steve on the Shurflo pumps freezing and just quitting. I have never had a Shurflo burn up from freeze situation they are die-hard pumps. I have ran them for years and they are like a Timex. Jabsco are good pumps too and I have had bad luck with Flojet pumps.

Just my nickels worth of thought.
