Can you turn the main Atwood Air Conditioning vent 90 degrees?

We are currently camping at Lake Havasu and it is hot! My 2016 FR3 30DS has a single air conditioner. By 1:00 pm it is not able to keep up with the heat and the FR3 gets pretty hot inside.

I am looking at the way the main air conditioning vent (the big square vent, not the small circular adjustable vents throughout the unit) is aimed toward the back of the RV rather than toward the dinette and coach where we actually sit. The only adjustment I see on that vent is to open or close the flow.

I am wondering if I could rotate this vent 90 degrees so that the air is aimed toward the dinette and couch. I know this would mean drilling a couple of holes, but would there be other problems I would encounter? Has anyone tried this?

The big vent is called 'Quick Cool.' After the room is cool, close it and let the ducts get the cool air.

No you cannot, the air intake/filter wont line up anymore when you do that...

Cover your vents with Camco insulation pillows helped us a lot in South Florida before I added a 2nd AC. Also, cold beer. Ice cold beer.

Thanks RK06382 and Dutch RV - Will give both suggestions a try. Most looking forward to the ice cold beer suggestion.

I read in another thread about using Reflective Roll Insulation behind the shades to help with the heat. I bought a roll from lowes to use for blackout shades for Alaska's midnight sun.

Lowes: Reflective Roll Insulation

Awnings are also helpful on the drivers side and bedroom window. That's on our to-do list. Meantime, we put auto windshield sun screens on the driver side and bedroom windows. Makes a,big difference

I will be there in late July and I’m preparing for the worse. 16 30DS with only the 18,000 btu ac. I know that will not be enough so I ghave lined the crap out of the rv with reflectix with camcorder vent pillows. I plan on bringing a portable 12,000 BTU ac with a nice insulated vent hose to knock that heat down. I must run that ac to the 20 amp on the pole off a 12 gage 38 ft cord. I’ve run enough tests to know that cord can handle the amps ( 10 max).

Have you thought about a quick homemade swamp cooler? Check out YouTube vids. Those work very well in dry heat.

Finch, you using Reflectix on your windows? You can also run a blanket across the front bunk behind the two front seats to isolate that huge front windshield heat ( even with reflectix on it). Your rv will turn into a cave, but at least it will cool down.

Finch you can also spray your roof rv down with water from your hookup which also drops the heat down

Finch create a deflector out of Duct tape and cardboard to redirect the air flow. You get better cooling and more air flow when you dump the air directly off the unit rather than the vents, better efficiency. Also, clean your ac vent and if possible take the cover off from the inside and make sure the common wall between the outgoing cool air and the return air is separated from each other. If not your cool air rushing in the rv will get sucked pass the common wall and will get sucked into the return thereby losing efficiency.

Have a Reflectix question...have heard that, if your camper has tinted windows, the Reflectix placed shiny side out can harm the tint. Comments?
