Jayco SLX trailers - how are they holding up?

I had a 2012 184BH and had to sell it last year. The side A/C was only 5000 BTU and could not keep up when over 80 outside, jayco put a bigger A/C (8000 BTU) in the newer models, so that problem should be solved. I was told that I could not put a bigger A/C in mine as the wall was structured around the A/C and could not be changed. The other problem was that the refrigerator would not stay in the safe cool zone if above 80 degrees outside. I did fan mods and it helped but not enough. Some had Jayco take them back to the factory, the last I knew, they had not figured it out. Go to Jayco owners forum and search there for posts by myself and others. I was sad to have to sell it, the rest of the trailer was good quality, loved the floor plan and size, just could not use two important things, the A/C and the fridge.
