Cooling a bus
My friend has a company that uses a full sized 42' pusher school bus that goes around to daycares and has a bunch of gym equipment inside that the daycare kids play on.
I am currently finishing a smaller 30' front motor skoolie build. I have insulation, 2 maxair fans, a DC AC, tinted windows with blackout curtains.
Sitting next to each other my bus is noticeably cooler without using fans or ac.
I installed a RV AC unit in the middle of her bus because I originally was going to install 2 in my bus but opted for a 2nd fan instead.
I understand that one ac unit is not suffecient to adequately cool her bus. We have a 43' 5th wheel and it has 2 units and struggles when its hot outside and it has insulation. She originally tried closing all the windows like you would in a house but aside from the area directly around the AC it really had little impact on the overall temps. She may end up adding a 2nd ac but she asked me if there is anything else she can try.
I'm wondering if opening windows in the front and back of the bus and using a couple fans would help.
I originally told her to park in the shade but some places dont have shade.
Any creative ideas would be appreciated.
The pictures are of from my bus. Almost complete.
