Sherwin Williams sells paint that reflects 90% of the sun's energy back into space. I am going to buy a trailer with an aluminum roof and paint it. I specified a 90% reflective membrane roof for our sun room remodeling project a few years ago. I doubt that is what the RV makers are using for roofs. If they were using a cool roof, they would promote it.

Any rooftop unit that is faired in on the downwind side will be much better. So I'd leave your current unit in if it works, and do what orbywan is doing here.

It can be screened or louvered to keep the flow attached but allow flow for the AC to work.
you could spends some $$ here for aero and end up saving, vs getting a new AC unit. A complicated electric door system would still be less expensive.
Many thanks to orby here.
Edit: sorry about that bad link.
