During the day, with 90+ degree days, we can get the inside temperature down into the 60s. I am experimenting with leaving the roof vent open some to try and "trick" the A/C into running longer and thus dehumidifying better overnight. I still have not found the "sweet spot" however.

Yep, that is the problem when you go with a one size fits all solution. Unfortunately our trailers are not insulated as well as our homes and the climate that you travel in has a great deal of effect on the inside climate. Quite honestly if you travel is in the cooler climates of the country, the standard sized air conditioner for your model of trailer may be too big. Likewise it might be too small if you are in hot full sun climates.
I took the approach that I'd rather be oversized and deal with short run times and some humidity, than being short cooling. I've lived both and I felt that dealing with the hot temps would be more advantageous. With that in mind I upgraded the cooling in my Classic from the standard 13.5 unit (which was standard at the time), to the optional 15K unit. It ended up being a very wise choice and Ive had no regrets.
For anyone purchasing new, I'd strongly recommend thinking the air conditioner through carefully. Don't take the trailer on the lot if you think the air conditioner isn't going to perform for you based on the climate and camping facilities that you use.
Also note that awnings can make a difference and if you have a patio only awning, consider additionals to keep that sun exposure to a minimum. Sometimes a longer awning covering a trailer with mostly aluminum exposed can assist in keeping indoor temperatures down. My Safari had a long street side awning even though it had two small windows on the street side. I added that awning after an ill fated first trip in 104 degree full sun. The trailer could only hold 86-88 degrees during the hottest time of the day. The awning turned that around and I never had issues again.
