Bedroom AC units will ALWAYS be colder output than living room area units. The reason is, EVEN with a common duct. The bedroom turns over a smaller volume of air. Which yields colder temps. Now, you state 1 is duct and the other has a ceiling kit. Explain that. Usually the bedroom is the ceiling kit AC and the Kitchen/LR is the top mounted AC. Did they combine the ceiling kit AC to the Ductwork? Swapping the units will not yield better cooling. 13.5 is 13.5. They either WORK or they do NOT. No partial cooling. So, as Chris stated, odds are you have a installation error on the one not cooling correctly. Which points to the RV dealer Techs as incompetent, as they should have the knowledge to test the Roof units before they replace. Untrained/incompetant people replace parts when they have no knowledge of what they are doing. I would try another Service Center. Doug
