Thinking of replacing my Coleman Mach 3 AC...it seems to be struggling now to keep up with the warmer temps. I have a 2004 Keystone Laredo is there an AC system that I can use to replace the Coleman?

Hello Daniel,
This year the refrigerant in the RV air condition went from the R410a to the R32. The R32 is much more efficient, making it better for the environment, and in return better for the consumer. The downfall to the new refrigerant is that the old R410a parts do not work with the new R32 parts, so it will require for you to get a whole new set-up.
The Advent Air Low Profile RV Air Conditioner System - Single Zone - 15,000 Btu - White - R32 # ADV82SR that you were looking at would be the whole new set-up you will need.
Or you could go with the Furrion Chill HE RV Air Conditioner System - Single Zone - 15,000 Btu - White - R32 # FR83TD. As of now it looks like we can get this one to you a little sooner, you will need to check the ETA dates on the product pages.
Any big adventures coming up in the near future? Where are you headed? Or better yet, what has been your most greatest adventure?

Thanks for the recommendation. Is the Furrion Chill Cube an option? I've looked at reviews and really like the low power consumption. Thank you
