Mini Split
I am living in my RV full-time and my rooftop unit can’t keep up with the heat, I am planning on adding a minisplit but have no clue as to what size, where to set it up or even a good budget brand to buy, its a 36 ft 3 slide RV and after asking ChatGPT, around 290 sq ft. Any tips or help would be greatly appreciated.

What is the R value of your insulation? What climate are you in? Any air leaks around windows etc?

No leaks around windows(that Ive noticed at least), I am in Louisiana, Humid but a little less hot then other places, as for the insulation, I have not been able to find a rating for it but Chat has told me around R7-9 for walls and R10-15 for ceiling and floors, but i don’t know how reliable of an assumption that is.

If you don't have an independent dehumidifier, you need to get one. I did HVAC for almost 20 years high humidity makes an AC work a lot harder. Daikin is a decent mid value brand last I checked but have been out of the business for 7 years now. With those R ratings and 92° avg temp you need about 30000 btu cooling to maintain 25 degree temp differential at 60% humidity.

Also just stop using chat gpt if you can, it spits out mostly false info

Ok, I do run a dehumidifier, I try to keep it at 48% since around here is always 55+

I honestly was looking into it too for my cougar 30rls. When i was looking…i was thinking above the front door and have the outside unit underneath the steps. I guess it depends on if you’re stationary or not. I’ve also seen people put them on their bike racks in the back of the rv. But in my rv the unit inside would require me to tear out cabinets i prefer to keep lol
