A/C in the underbelly am I crazy??

[ShawnH]

I have been having a load of fun trying to insulate and block all of the ways heat is traveling into the cabin from storage compartment and under belly. It was coming through the vents in the steps,through vents in the floor and also through the bathroom sink.
Well today I just decided to place a portable A/C unit inside the storage compartment after I removed the panels to the electrical and pluming.
Has anyone done this before?
It gets 100 plus here in south Louisiana during the day and there isn't any shade to found at the park I am in.
So right now I don't know if I am a genius or an idiot.
There is ice cold air coming from my heat return vents at the steps, so there's that.
Thoughts and opinions welcome

The best way to think about AC is exchanging hot air with cold. Generally, the air that most needs replacing is up high.

Where is the exhaust of the portable A/C unit going? If it is also blowing into the storage compartment you won't gain anything.

If you somehow have it hanging in a storage door like a window unit then every little bit of cooling helps. If it has hoses and that is all that is blowing into the storage area, that is even better.

Pedestal power is often a concern when trying to run several A/C units. You can overload things quickly.

We often use a portable fan near the floor to help push the cooler air upward and around in the R/V.

I have the exhaust routed down and out through where water and cable lines come up into the panel. It has helped tremendously, The inside temp during the heat of the day has dropped 15 degrees and allowed for the main units to kick on off like they are supposed to do instead of running nonstop.

Thanks for the clarification.
Sounds like it is helping tremendously!
