But it's a dry heat...So is an oven's heat.

Run both units and try to get it cold in the morning, so hopefully, you only lose ground slowly over the course of the day.

Not much chance in Phoenix but can you find a shady site?

Can you adjust the air/con vents so they focus all the cold air in one part of the rig? We've closed the bedroom off during the day and opened the direct venting, so the main living area gets the bulk of the cool air.

Pheonix in August. NO way in literal HELL will your RV's AC keep up.

It has problems with 90's 100's are beyond hope.

And remember folks. it's getting hotter out there.

Most techs will tell you the A/C is good for lowering the temp 20°. The first trip we took to Arizona with our two dogs, it was difficult to keep things cool. It was recommended we put the silver bubblewrap (insulation) in the windows. It's available at Lowe's or HOme Depot. We did that and it helped immensely. If you are in the area a lot, I would even line your cabinets with it. I have not done that, but people say it helps a lot to keep not only heat, but cold from permeating the coach.

Your generator should definitely be able to handle both A/C's. I would run them both and keep those doggies comfortable. The alternative as has been suggested is doggie daycare or a pet friendly hotel.

1. Don't go to Phoenix in the summer.
2. If you have to find shade.

These solutions are free...

Putting the bubble insulation on the back walls of the cabinets is a good idea. I haven't thought of that. Our pantry and closets get HOT.

I have reflective bubble insulation covering all windows, insulated "pillows" covering the 3 roof vents, layers of heavy thread count white linen covering the shower skylight and the best I can do with 1 15K AC in a 32' FW is 16* less than whatever it is outside. If it's 100* outside with the sun beating down on the FW, it's going to be about 85* inside. It Is What It Is

AC cant drop the temp 45 degrees. Maybe 20 at best if well insulated etc


Yup, 20 degrees is it. If it's 115 outside all you can do is try to enjoy the cool 95-degree comfort of being inside, while you pull out the map and determine your next destination!

You really need to park in the shade somewhere that will help big time...

What cooling you gain during the night gets immediately eat up when the sun comes up if you are not sitting in the shade somewhere...

I remember my Maricopa days... It is a brutal place to stay for sure...

Our Air conditioning back then was water based haha... Had to go up the roof to change out the filter and had fight off the black widow spiders first...

There is no such thing as a 20 degree drop FROM OUTSIDE AMBIENT TEMPS. The 20 degree is the INSIDE differential. Here in Texas when it is 105 degrees, a standard Motorhome with 2 ducted AC units will easily get the interior to 75 degrees. I DO THAT ALL THE TIME WHEN I AM WORKING ON THEM. When I am getting set up to work that day, and it is HOT(100 to 105), I stage my units on our lot and turn on the AC units and max cold so when I pull them in it is cold/cool in the RV. After a few hours it is usually in the 75 to 80 range. NOW, to the OP, her unit is 15 years old. She NEEDS the AC units checked out by a qualified RV AC technician/shop. Odds are one of the 2 units is NOT operating and cooling. I state this from her post that stated Genset ON and could only get to 99 degrees. Doug

Close the slides if possible. Move to Flagstaff where it is 20-30 degrees cooler.

20 to 25 degrees cooling is normal IMO.
