Nice and Cool
The Mach 10 fit perfectly! Coleman said the mounting holes may not match exactly but they did. We left a control box, that mounts into the Styrofoam in the roof, out of the hole. We were able to work it into the hole without having to take the entire AC off the roof. Heat pump works great, AC is nice and cool. It took us about 3 hours to complete the job and we had no idea what we were doing. I think we could cut that time in half if we ever do another one.
