Does Coleman-Mach Underbunk RV AC Come With Tubes  

Updated 03/12/2026 | Published 03/07/2026

Question:

What size is the vent on, the side with the electrical cord? Or do I need tubes to run off the 3 holes to make the vents? Does it come with the tubes?

Hi Angela; you will run air ducting (not included) off of the openings on the side of the Coleman-Mach Underbunk RV AC # CM62RR. I recommend getting the All-In-One kit # CM82RR which includes all of the accessories you need for installation. The unit will install in the floor and does require some cutouts. I went ahead and attached some pictures below from the installation instructions for your reference.

Where will you be installing the AC?

Thank you for the information. That helps a lot. I am planning on installing under a dinette bench.
