Closing duct runs that run past last vent
Our 36' TT only has 4 AC ceiling vents(MBR, Bath, LR and Bunkroom). It has a 15k BTU AC. When I popped off the ceiling vent in MBR and Bunkroom the duct works continues past the vent 3-4'. This see...

I was tickled pink to find my 5th wheel duct work extended from one end of the trailer to the other. My ducts are just a cut out in the ceiling foam - not a PVC thing at all.
This is where I run my RF and VIDEO cables from the home entertainment center to get to the other points in the trailer. Both ends are accessible from ceiling cabinets with minor mods to the duct walls. Once inside the ceiling cabinets I was able to completely hide my RF and Video cables going to where they needed to go...
I have run several RF cables thru them. Pull down a couple of vents and fish the cables thru using each of the vents to pull the cables. When I get to the point I need to come out of the duct I seal off good with foam spray. My home entertainment center is almost at the center of the trailer and was easy to punch thru the duct wall to route cables from there. After the cables were installed then I sealed off good with foam spray. No added cables are visible anywhere in the trailer.
My added cables doesn't seem to bother the air flow any at all...
I suspect the lengths of the ducts has to do with static air pressure of the system. Probably an engineering thing to insure the same air flow pressure from each of the ducts when in use... Messing with the static air flow may help one air vent big time but kill the air flow on the other end??? Just my thoughts...
