Ducted vs regular air

My husband and are are discussing options for our next trailer we would like to buy.
One aspect we are having trouble understanding the difference between ducted and non ducted air conditioning.
Has anyone had both? Was their a difference? My main question has to do with quietness... Is the ducted any quieter?

The ducted air cools the whole camper more evenly, as there are vents all along the ceiling, and it is much quieter as the vents are far from the fan in the air conditioner.
But I have found that when first setting up and trying to cool the camper down, it will cool faster if I open the vents on the air conditioner cover, as there is much less restriction. That is when I notice just how noisy the fan really is.
So, ducted air is best, as you would still have the option to open the other vents as I described.
My only problem is that our ceiling is so high that I need a stepstool to reach the air conditioner!

Definitely like the ducted best. Not sure about newer campers but the older ones that were nonducted had no thermostat controls. You were either on low/high or off. The fan blowing all the time drove me nuts and if you were in the room with the a/c it blew on you the whole time..... When we started shopping for new campers that was a definite must on my list.

i much prefer ducted over non.
for one thing, there's no big square thing to bump your head on.
second, you can close specific vents to focus the cool air into certain areas of the RV.
third, you can slide a tab and the grill will blast air from the center, just like the non-ducted type, if you want.
fourth, being able to use one thermostat to run the a/c and the furnace, is more than worth it. just like at home.
and finally, it is much quieter than the non-ducted units.

my unit in the bedroom (5th wheel fdw). is thermostat controlled as far as the compressor is concerned. the fan runs constantly.
it came in handy at the last campground as a noise block. (we tend to like to sleep in. those that are heading out usually like to get an early start. that noise tends to be blocked out).
i believe if i had mounted a remote thermostat, the fan and compressor could cycle together.
one other advantage of separately controlled units is that u can zone heat and cool (my fdw unit is a heat pump).
ducted a/c was a must have on my unit as well. after having a non ducted trailer in the early 90's, i wasn't going to buy another non ducted.

It depend on the size of the trailer you will buy also. Generally the ducted type ac model is reserved for trailer over 25 footers. If you want a trailer less than this size the only option is a non ducted model. I would prefer the ducted model but our trailer is just over 20 feet and we had no choice on this decision.

I have both as mentioned above, start the unit with massive air flow coming straight out of ac unit ,then after it cool down a bit, slide the louver on the ac to allow the cool air to flow thru the ducts to cool every square inch of the camper with much less noise.
