I guess I don't know how to ask a question. I understand the benefits of ducting. I have had ducted AC in some of my trailers and fifth wheel trailer. I am curious as to whether the amount of heat gain from the ceiling ducts matters when it comes to cooling a travel trailer with no partitions. I also know that non-ducted is noisier. It just seems like this trailer gets a lot cooler a lot quicker than my last two which had ducted AC. Might be all in my imagination, but recent 100 degree days have not been a problem.
