The Columbus rigs have the Dometic Comfort Control digital multizone like this. Dealers don't set them up correctly and many of the extra features don't exist like humidity control, outside temp indication, etc. They are goofy to understand for the non techy types of owners. Many of those same low tech owners have a heck of a time setting up and running the home theatre system also. However, a 20 something year old video game playing online junkie in the campground can set it all up in 1 hour or less.
