AC unit won’t keep trailer cooler than 83 at night ! Any ideas ? I checked top unit every thing looks good! It can’t cool when full sun and 95 in FL , lol ??

The plain simple fact is, 1 AC will NOT cool a RV over 26 foot, especially if you have slide rooms. Does NOT make a difference of BTU of AC unit. Are you ON 30 amp and only have a 30 amp RV. or do you have 50 amp service using a 30 amp Shore CG receptacle? Don't blame the AC or FR, Blame the dealer that ordered this size unit without 2 AC units. You may have AC operation problems or installation/ductwork problems, but does not matter as I stated, you have an inadequate AC system. Doug
yup I agree completely. shortly after we bought our Outback 295RE (32 ft double slide) Keystone added provisions for a second AC unit and made 50A service optional. Note I said "after".
But ours is a single unit Coleman Mach III. With all the mod's I've done it is barely adequate for us in our climate. A climate that usually sees night time temps in the high 50's, low 60's, even in august and usually stays below 90 in the day. for those conditions it can keep the trailer at a set temp but runs most of the time. If we hit days with temps in the high 90's and high night temps, it won't hold temp, and will rise in the afternoon. And on these hot days it's usually noon before it's above 85. A few years ago we were camping when day highs were 105, night lows in the high 70's and by 10am was pushing 90. It was miserable, AC ran constantly and inside temps peaked in the mid 80's and even by 10pm was uncomfortably hot.
As shipped without my mods to clean up and insulate the ducting, add more ducts, improve airflow even temps pushing the mid 80's would cause the AC to struggle. And even improving airflow has a limited affect. more air movement but the same cooling BTU so can help cool down rate some, but not ultimate heat extraction once airflow reaches a certain point.
