Added a mini split to the rear that runs in conjunction with the 2 roof acs in direct sunlight I can maintain 66 degrees with temps above 95 in 70% humidity.

Can someone post a diagram or something so we can better understand how to fix this problem?

Also in extremely hot temps should you run fans on high or auto?

I know these seem like silly questions, but your experience is appreciated! Thanks!
Search YouTube.
This one shows an early model Montana HC.

I have a 2019 3130re. I have 2 return ducts and they are very solid styrofoam. No evidence of collapsing. I have read of people adding a 3rd return duct in the middle. Do your research first.

I noticed a definite difference after putting reflective film in my windows.

Interesting article about window film. If you have dual panes, adding reflective film to the inside could be problematic.

I once found a link to supplier of exterior, bronze reflective film (to match the Monty) but I lost the link and can't find it now.

I've been wondering when the RV industry would jump on the minisplit idea.

I assume yours is a customized solution?

I chose the Mr. COOL DIY. I'm currently stationary but chose the 18k btu that's 220 volt. Max amp's is 20. It's been an absolute lifesaver.

Before installation, 95 degrees outside both ACs running all day, temps in coach would slowly rise throughout the day. Today it was 95, only the bedroom ac a portion of the day and lowered the temp 2-3 degrees over the course of an hour.

Yesterday, same temp running all three, it lowered it 7 degrees in an hour.

Mr. Cool has a 12k btu @120v with max of 20 amps.

They will jump on mini splits when they are cheaper than the ones they are using now.
