Cold Weather RV Trailer Living Prep Tips

A few years ago another job.
Heavy snow trashed hundreds of trees in a campground.
We stayed in a log cabin that was heated with a pellet stove.
Worst 2 weeks of my life. Cold,damp,no water and the septic line froze solid in the first 4 days. Dealing with the forces of nature in that case was a losing battle. Dealing with temps near zero farenheit or colder requires a whole different game plan.
Had the brains of the outfit spent time preparing for this situation the outcome would have been much better.
