New to RV lifestyle, need to know if this is normal

Greetings all!

I tried a search and didn't find a good answer to my question so I hope this is the right area.

I have a 2015 Keystone Sprinter 299RET. It has a 15k BTU AC unit and prepped for a second. Now I am actually a certified Universal HVAC tech (haven't touched an AC unit in 30 years though) and while I know how AC units work, I am not familiar with how they work in an RV.

Our unit isn't cooling the coach down. It's working and blowing cool air but before I go yelling at the service department or asking for a warranty replacement, I need to ask this question.

What is a reasonable coach temperature that can be expected on a 85 degree day, moderate humidity in direct sunlight?

I have had the unit running on 78 degree days and it's 74 inside with the unit running on high. Recently, it was 87 outside and 88 inside. The people with a similar size coach with one AC on the same day had their coach inside temp at 70. I suspect I have an air leak somewhere. I used a laser thermometer and found hot spots inside the air return prior to the evaporator. I think that is my issue. But what is a realistic temperature I can expect on my size coach with one AC on a warm summer day?

Thanks!
