Living in the desert myself, I will say that is oppressive heat. I think your system is doing pretty good in that heat. Camping at Zion 10 years ago temps were around 105° we moved down to Coral Pink Sand Dunes temps were 118° our dual AC ran 24/7 but we had 30 amp to power them, do you have 30 or 50amp? While at the Dunes we were having trouble, the advice I was given was to shade the hot side of the RV as best we could and bring the slides in. We did have a tarp and a sunshade that we put about a 45° angle that really did make a difference in helping our AC, but moving the slide in helped too as it removed that much volume in the RV that the AC had to keep cool.
Best advice I'll give, move. Get out of the heat or try to find shade, but moving is the easiest right now.
We were at Zion last week and it was crazy hot (85 when we finally left at 04:00 on our last day).
We were there for a week and had one neighbor on our east side the entire time to give us some shade and then revolving neighbors on the west side to give us afternoon shade.
One of the neighbors on the west was a shiny new large Class C. I was grateful for his shade at first, but then when they packed up and left our rig actually cooled down. I didn't see it at the time, but the morning sun from the east was reflecting off their rig and heating us up. We were actually cooler after they left and a smaller rig replaced them. I never imagined that the glare from their clean rig would heat us up so much.
