Expert Reply:
Welcome back Steve! The Coleman Mach-C Everest Air Conditioner System item # CM35MR in white or item # CM55MR in black can both be used in a trailer without air ducts. These systems come with an air distribution box with built in vents that allow air to flow through them into your RV.
These are complete AC systems that include an 18k variable speed air conditioning unit, an air distribution box that works in both ducted and ductless orientations, and a thermostat that will control the AC and even a furnace if your trailer has one.
What kind of trailer do you have and what climates do you typically camp in? Feel free to answer this and throw in any other questions you have, where it says Add Comment.

Thank you. That's what I thought but I wanted to be sure. I did not think to ask that about the furnace but that's helpful as well. I have an older Grand Design and we travel all over the country in it so all climates to answer your question. We did spend time in Florida over the summer and realized our older Coleman Mach was not keeping up as well.
