A/C couldn't keep up. Help?

I'd be tempted to get a mist system to assist the air conditioners. There are some that do 1/2 gallon per hour per nozzle.

The only place in my RV world where I tripped a breaker, inside my rv, was on Mesa AZ on July 29.

If you have a way to monitor voltage--set the fridge to propane--and try running just one air conditioner on the 15 amp shore power. If the voltage stays at 108 or above--then you are fine. Do check voltage often.

Do you have a tarp you could place over the front windshield? If not, pick one up at a dollar store.

An evaporative cooler will make things worse, not better. It would counteract the air conditioning system that actually removes moisture as part of the cooling process. What might help a bit would be to spray the outside of the rig with water occasionally. The tradeoff would be a whole lot of hard water staining. Covering the windows with reflective sun shades and having the AC units cleaned and serviced would be my first steps.
