Do you have 13.5 or 15k but AC? We had 13.5 and had no issues keeping our 30' tt cool in FL last August (just as hot). Only problem we had was condensation. You could try closing curtains.
We have 15k from what I see in paperwork. Curtains have been closed all day. Only mistake was fan was on low not high. Should we have the vents directly on the AC unit open or closed?
We run with the AC vents out of the AC open until it is cool and than close them

I was in Gulf Shores weekend before last. We have a 15k AC but still the direct sun can be brutal. We did ok with fan on high and at least one of the vents directly on the AC open during the day. I found if I opened the vent that was pointing to the side of the RV being hit by the sun, it did better. I also learned that my ducted vents ended some work. There is a whole string on here about that.
I found the A/c stayed on most of the time except for at night when it would cycle. Even then I kept the fan on high as opposed to auto to keep air moving.
We were having a tough time last week while we were at a park with no shade. We had to leave the fan on and the air dump open. I also had a floor fan running. Once it cooled down and stayed on the next day it was better.
Camping in upstate NY in the summer if it hot - 85 to 90 degrees a single AC will not keep the trailer cool. Heat up to 80 and then cool down when the trailer is no longer in the direct sun.
If I lived or camped down south in the Summer I would have a 2nd AC. We have a fantastic fan in the bed room instead of the second AC unit.
We were up in the Dallas area during the entire very hot summer of 2012. At the time we owned a 35' Cruiser with one 15k a/c. The unit would come on at about 9 am and run continuously until about 1 am when it would start cycling. It cycled through the night until about 9 am. We kept our awning out while we were in the area and no wind was forecast and shades down. The inside temperature during the day stayed about 80. At night it would cool down. It was never uncomfortable for sleeping. Just something expected in hot temperatures with one a/c.

You can try cutting some of that reflective foil insulation to fit the windows that face the sun most of the time. It really cuts down on the energy needed to keep the camper cool/warm...downside...can't see out the windows....

In the old 5er with the option to use the direct air dump or the ducts, that we would get much cooler much faster with the air dump cooling the interior of the rv rather than cooling the ducting
Yes, once it caught up, we could close the air dump and use the duct work...
(oh, and I too, found that the overhead ducts were not sealed very well, in fact, one end was open to the 'attic')
