Thanks for the responses. I believe the DC inverter unit being mentioned is probably a mini split-ductless system? They look very intriguing but I can't find a place to mount the interior unit without blocking cabinet space which I don't want to do. Suggestions on a 25RQ?
Chris, what a/c unit do you have?
The original unit was a 11k btu and worked hard on hot days. I don't think I would even consider anything less than a 13 btu and most likely go to a 15k.
The 13k would be desirable because Atwood says that their unit can run on a 2000i generator
which would be nice. But if it struggles in hot climates, then??? Most of our camping is boondocking
and sometimes it can get rather warm, even in the mountains.
Thoughts on other air conditioner brands than Atwood?
I have a chance to purchase a 15K Coleman Roughneck Mach 8 made in late 2014 or early 2015 for $500.00. The seller says he bought if for use with his truck, but never installed it. I haven't read good things on Mach 8s. Compressors going bad, noisy even though there are kits to substantially reduce the noise, and fan blades breaking! I would be with in a $100.00 of the cost, with the upgrades, of the 15k Atwood heat pump. And a 2 year warranty, where as the Coleman would be ZERO! Seems like a no brainer.
Thanks again everyone! And if anyone has installed a ductless in a 25RQ, care to share with installation and photos?
