We camped in 109 degree heat last year for two cloudless days. The air conditioner worked great but lowered my blinds on windows that were receiving the sun and always left my awning extended to shade the curb side of the TT.
My fridge was "right on the edge" of not keeping up. This year I'll probably invest in one of the "coil fans" and blows air up along the backside of the fridge coils. This should help the ammonia condense and help the fridge cool easier.

Your biggest concern should probably be for yourself and whoever else is with you. Heat stroke is a real possibility in that kind of heat. Stay out of the sun as much as possible, drink LOTS of liquids (especially water)and watch drinking too much alcohol as it can dehydrate you more quickly. Stay covered as much as possible, including hats. Wet towels on the back of your neck can help bring body temp down a little. And watch that your pets have lots of water too.

Shade would help. Face the trailer so the awning will shade the side in the after noon and as the sun sets. If the park is full watch the voltage stays 108+.

Set up one or two small computer fans on the cooling fins of the frig. Keep the blinds closed on all windows. Run both 24/7

I use Tom Kat's suggestion and fill a pot or tub with ice. I also freeze water bottles ahead of time and leave them in the fridge. At night, I move the water bottles to the freezer and back down in the morning. To minimize the opening of the fridge, use an ice chest for drinks, fruit etc. If you have a choice, park your TT with the fridge side facing north (shady side).

ps- then I ask myself, what the heck am I doing camping in the desert when it's blazing hot!

One thing to remember about these A/C units... they are not as powerful as those designed for your home. My owners manual states that the best these units can cool is to 20 degreees less than ambient temps.
So, if its 110 outside the best these units can do is cool inside temps down to 90 degrees. I would think having plenty of fans going would be helpful.

I think the 20 degrees means if the RV is 75 inside the air unit will blow air at 55. The outside air is not drawn into the RV. If it extracts more heat than what comes in it will be able to hold the setting. And yes it is possible with an underpowered system to only cool the inside to 90 when sitting in 110 degree heat and blazing sun.

I ran my air conditioner full time last summer at 114 degree weather for a week straight. My wife was with me and needed to stay cool while I was working. She said it stayed down to about 80 during the day. That is bearable in that type of heat. I have only 1-15,000btu air conditioner on a 30' 5er. No problems, and the fridge was always cold.

When an A/C freezes up it is an indication that it is low on freon. It should be serviced.
