Eagle Helix cooling system

[Together]

Greetings,
We had a Jayco popup in the late 70's. Terrific unit, our family of six always had a great time. We're now looking seriously at an Eagle 338rets - my question concerns the Helix cooling system - I'm getting mixed reviews, should I be concerned? Our new 2017 Eagle 338 will have 2 ac units 1-15k & 1-13.5
Thank you in advance for your experience.
Bill

Why not 2 15,000? The price difference is minimal. Our 2015 PINNACLE 38FLSA does fine in the FL sun with 2-15,000 and it has the "Quiet Cool".
