Good thread, I have learned that 2 people are within an hour of me in ATX!
As I read through this, it is really 2 threads ongoing-
1- How do you handle cold weather on a coach that is parked/stored
2- How do you handle cold weather when the coach is actively used, either at a park or driving.
The first has been covered a considerable amount on here from my searching and time on this forum, so I won't address that.
The second I have not seen as much, and I would like to know more about this. If you are driving in a cold area, either passing thru or perhaps you are living FT and in a park, if you keep the coach warm enough for the occupants inside by whatever means (electric heater, gennie running, propane, AH), will that be enough to keep the basement area warm? I know the propane has vents to the basement and assume the AH has the same? (IDK since I have never seen how the AH works/vents, so someone can chime in as I am curious about that). But if you use electric heater, either the standalone Lasko types or the roof HVAC, will the warm air in the living quarters be enough to keep the underside from freezing? I think it is realistic to assume people will be at a RV park with an electric connection would not use their propane/diesel, unless the electric methods could not keep the basement warm. Specific concerns are all of the tanks/plumbing.
I supposed some wireless temp sensors underneath would be helpful to monitor. I have 2 and been waiting for some time before giving a review on both. Of course, YMMV.
1- Amazon.com: ORIA Indoor Outdoor Thermometer, Digital Hygrometer Thermometer,... On recommendations of others, I got this last year. It works but the range is not as long as I would like. It struggles to go through numerous walls at 40 feet (coach>outside of house>2 inner walls). I have had to get up and go to the window of the house closest to the FT and wait for it connect. Not ideal at 3AM and takes several tries. I would not recommend this unless you will be in the coach with it.
2- I recently got this from Ambient, it works great, much longer range than the above. No issues as all. It also has an audible alarm when it reaches a certain temp that you set, mine is set to 36F. As you may know, Ambient is a leader in weather stations and it says it can do 100 feet. My only (minor) gripe is the monitor is not backlit, so in the dark it needs light. I just use my phone for a second in the middle of the night. Robot or human?
