Now that's a question we can work with!
Unfortunately, your roof AC will not compare to your Jeep's system for many reasons, but to make it better you have to handle the heat input.
Sounds like you have a good start with reflective window shades for the windshield and closing the cab curtain. The suggestion to block the 14"x14" vents is good as well. That just leaves the side windows. A lot of people just buy the reflectix and cut it and put it in the windows.

I went one step further and also purchased a corrugated panel:

Apparently no longer available online but may be in your local store.
Cut the panel into sizes that fit my windows, used spray-on glue and glued the reflectix to it, and used these panels in the side windows to cut down on heat input.
Parking your coach in the shade is also a huge help.
With my ACE 27.1 and 15K AC here in Florida, on a 95+ degree day sitting in direct sunlight, I can turn on the AC at 3:00 pm so I can start working in it at 5:00 PM. When I first turn it on it is over 100 degrees inside, by 5:00 it is in the 80's but realize you are not just cooling the air in the coach, but everything inside it as well as the walls and roof.
While camping, or if I start the AC first thing in the morning, I can easily keep the coach temps in the low 70s (where the thermostat is set).
I hope this helps.
