We had a Jayco with one of the "dump" type AC units in Colorado for 2 years and didn't have any issues with cooling down the unit even on days they call hot there, it was just noisy. Our 25MLE Cougar has two ACs instead of the one and both of them are Mach Q units which I simply love because they are so quiet. We took it to Colorado last year and had some issues on one of their "hot" days. It just felt like there wasn't enough cold air coming out of the vents. We are from Kansas which is way hotter than Colorado but we didn't get to take our unit out during the hot months last year locally.
Long story short, I just placed an order for the KoolRV upgrade that is supposed to improve the output airflow. I've read mixed reviews but thought for $85 I'd give it a try with one of them and then the other if it seems to work.
Cool Down Your RV with A/C Connect for Coleman Mach Series - KoolRV®
I'll post again when I get it in with some unit specific installations pictures and results.
