Reading the OP post was sort of confusing. If it is ducted, the ducts may be made from a fiber board or insulation board. The ceiling may be part of the system and the vents may be just attached to the ceiling.

How about some photos of your concerns.

Sorry to confuse. What I mean by ducts is small lines of tubing similar to a dryer exhaust line leading from AC to each ceiling vent.

So what you are saying is that the entire "Attic" (as they describe) is one big Duct box ?

If so, then that is the possible reason why our front ceiling vents are not blowing out as much air, the back ones are blowing out alot. its then unbalanced. Air will be forced out in order of least resistance and shortest distance. Since the back vents are closer to AC units it will blow out first. That is obvious by the results we are getting. Its freezing in the back and way to hot in the front. The one Montana was not like that.

Is there such a thing as vents that close in a 5th wheel maybe we can close the back vents and force more out the front. the vents we have will not open or close. We would have to tape each vent we want closed.

Sorry I am new and I will need to learn how to post pictures then I will

I have a link to Video if that helps but doesn't show ducts http://youtu.be/TKXu8yYzn1A
