We have a 37' fifth wheel that has a 13,500BTU ducted AC in the living room and a 5000BTU ceiling unit in the bedroom. When we arrive, I of course get the both AC's going ASAP when its hot out. It takes two hours with both running to cool off the RV when its in the 90's out. The bedroom cools quickly since the room is smaller but the living room takes forever. Both AC's blow cold, I've cleaned the filters in both. Seems to me two hours to get the temp in the 70's is too long for 325 square feet.
How long does yours take?
Thanks!

Sounds about right for the size AC units you have. I would suggest removing the AC unit covers on the roof and making sure everything is sealed keeping inside and outside air separate.

We always have a fan blowing along with the AC. Seems to help a lot. Two hours sounds about right.

From experience, if it's 113 outside. All bets are off. However, once you become eligible for social security the outside temp becomes a variable that you can change simply by adding diesel fuel. Come on October 1.

Have you tried running a couple of small floor fans to move air about - - that is the real trick keeping the air moving. Of course we never have to worry about cooling down when we arrive, ours is cool while we drive - on of the advantages of a motorhome.

That's about right! You have to figure everything including the closed cabinets and compartments are at the same temperature. These are not insulated like a S&B's and if your house air was off and was in side in the 90's. It would take more time! Also it takes more energy to heat them when its in the teens and 20's.

Only 60 days to go? Time sure has flown by... hasn't it? Seems like just yesterday you bemoaning 500+ days to go.
To the OP, do you have a generator you could run at least one AC while moving the rig to the campsite? That could take the edge off the heat build up. May cost a few dollars in fuel to run, you get to decide if the cost is worth it.

If you have the option, run a generator while on the road running 1 AC. That's what we do to help keep the house cool. Most AC's will only work to a 25-29 degree difference. Meaning they only cool 25-29 degrees less than the ambient air temp. If it's 100 out, 75-80 might be all they can do. Once your furniture, floors, ceilings, etc get warm, it takes awhile to get rid of all the built up radiant heat.

Mine cools down in less than 20 minutes when both are running

Wait for the humidity level; it will go down, it has to be low to cool; If it does not go down, it will be hard for the air conditioner to cool the RV.

Adding another second RV AC unit or buying a larger unit might help in cooling down RV more, but it will be an expensive endeavor. In its place, there are some cost-effective tips that you must know about to resolve this issue well. If you need I will share for you. Thanks!
