08 Kingston 33sk with one 15k a/c unit. I get great air flow out the unit itself but very little from any of the other vents throughout the unit. Is this normal or is there something that can be done to improve the air flow distribution?

Remove the vent covers and check to see if foil tape was used to seal each one, if not some of the cool air is going into the attic. Also, the main ducts typically run further than the last vent. While the end is sealed, there is no value in having the extra air space and possible turbulence, so using rigid foam board, add a new cap just inside the last vent. Finally, check for air leaks where the A/C connects to the main ducts and seal with foil tape.

Ditto what Larry said. I had to do all that to our old Cruiser and our Paradise Pointe because we were losing cold air into the attic space.

Does the main unit have louvers that you can shut? If so, closing these will also increase flow to the other vents. I have mine open to cool the living area quicker, then close it to cool the remaining spaces.

Hi, Russ. We are on our third 5th wheeler, and ALL of them have had the same problem as you describe. This spring we finally had a second air conditioner installed just in time for the hottest weather so far last weekend. Even though the outdoor temperatures were swealtering in the lower to the mid 80's, it was comfortable and cool inside!!Expensive, yes; woth it, yes!

Boy, with high temps in the lower to mid 80's, I'd be happy and real comfortable with just my single A/C. So far we have been over 100 about 4 days this year, something that doesn't happen til mid July normally. What I have learned that helps in very hot temps, set the tstat lower than you really want. With the new Dometic tstat, fan speed is determined by differential between set point and actual temp. So, a lower set point will keep the A/C at a higher fan speed and help it keep up with the higher outside temps. At night I will change the set point to desired temp so the A/C will run on the lowest fan speed or shut off entirely.

Look at the "Quick Cool" louvers under the unit. Are they open? If so most of the air will be deposited just below the a/c unit and diverted from the ducts.
BTW: It is very hot up here at RRLSP IDBU. We are comfortable and cool with our one 15K a/c. This is a brand new unit but the original cooled just about the same. I cannot be warm, especially at night and the one unit does a great job. It does run almost non-stop during the day but it is not my electricity I use.

Thanks for all the help. This is our maiden trip and still figuring out how everything works! I found the air deverter under the main inside vent! That was the solution!
Happy camping

We are planning to add second AC unit to bedroom. It appears the TV Antenna will have to be moved to make this addition. Has anyone had this experience? We will be doing a self install.
Suggestions appreciated.

Antenna moved, roof patched, 13,500 Polar in and working. Electrical is ran temporarily to a separate 15 amp breaker due to fact we only have 30 amp service. Does anyone know of any openings in framing that can be accessed to run the electricals or have any other suggestions. Love the new AC. We are chilling in Texas and that is something with all of our 100+ days currently.

Do the vent covers just pop off?

There is a tab on each end of the hinge when looking at it from on top of the roof. You need to bend up one tab, crank up the cover from inside so the slide mechanism, under the cover, can reach the slot to disconnect, then side to the cover to the end where you opened the slot.
