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!
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
