Residential fridge like we swapped to will solve all the fridge cooling issues. On the AC, we can maintain 72 deg inside in full sun / no shade, 96-98 deg outside temp, BUT, that's with several changes / modifications. This is with a single 15k AC / 33' rig. We've full timed in a couple of rigs, and keeping cool is a must, so when things don't stay cool, I'm axing away at stuff to make it work. I managed to get our 40' / 4-slide fifth wheel to maintain 72 in the same temps, but again, with several changes. It can be done. Some of the things I've done, people aren't willing to do as they're scared of voiding a warranty, or just don't like the change.
