Where did you turn for cooling comfort?
Window a/c?
Free standing unit that vents to the outside but stays in the room?
Bags of ice piled around? LOL

You seem to have ruled out a new rooftop AC, why is that.

The free standing in-room unit pulls in outside air to compensate for the hot air that it's pumping out that pipe. Well, the unit itself doesn't actually pull in outside air, but outside air HAS to come in to replace the air being pushed out. This means that hot air is being brought in, so these units don't cool quite as well as a unit that vents the heat through a radiator or some other method that doesn't require pumping air out of the room. I discovered that trying to cool my boat with one. It got coolER inside, but not cool.

I guess I figure they are quite costly and I guess I would just rather put my cash into things that make the unit go and stop.

New Coleman 15000 btu for $600, decent quality 15000 btu freestanding $400 and up. Add another $50 for hardware to hold it down and make a window insert for the vent. $150 savings is hardly worth the trouble imo.

Don't start down grading your rigs systems. Bite the bullet and replace the air unit. Some day when you are broke down beside the road in Arizona summer heat, you will be glad you replaced the air conditioner...that is if the generator still works. I know you have had your share of issues with your rig...I hope things get better.

check cragislist and salvage yards might get lucky

You keep asking for answers and help in fixing stuff over and over, if you don't like the answers why keep asking?

No comment to the above but updating post to add:

After the generator was installed, it turns out the rear a/c runs off it and that's why it hadn't previously come on lending me to assume it was dead.
Upon taking the unit to an RV shop that was recommended, he found out the rear cooled nicely and replaced the front with a brand new one altogether. Upgraded from 13k BTU to 15k, new shrouds on both, the new cover in the front and the cover that was in the front was transferred to the bedroom as it was broken in half from the get go.
Saaaa weeet!!!

I have been thinking of the possibility of replacing the 2 rooftop A/C units with a dual-zone ductless mini-split. They are far more efficient, far quieter, and use much less energy than the rooftop units.
