Keystone RV Forums - View Single Post - AC ducted vs non-ducted

Double checked with the dealer and both the ac layouts are accurate for the two in-stock units I am looking at.

Also have been having conversations on this subject and one person (who is anti-duct) said this about ducted ac in a 5er: Your ceiling does not have that much insulation around the duct work because, keep in mind, the space from ceiling to roof is only +/- 6 in at most. This causes the ducts to warm up in really hot weather increasing the temp of the air coming out of the ducts. Additionally, the further the chilled air has to travel from the unit through the duct to the vent, the warmer it is compared to the temp if it was being dumped straight out of the unit. Another point he had was that all the shifting and jolting around that occurs during travel time causes duct leaks in the ceiling making you lose cold air that way as well.
