AC won't turn back on
So I just bought a brand new Sabre 5th wheel. The A\C is blowing nice and cold for a while then shuts off. As as the temp goes up inside the camper you'd expect the unit to kick back on but it won't. ...

You say it's a new trailer. Has it ever worked correctly?
The air conditioner(s) may have a "freeze-stat" that's not installed as it should be (stuck in the coil fins). When it stops the compressor to let the coil defrost, it's a signal there's something wrong. You have to cycle the thermostat to reset whatever safety device it was that stopped the compressor. Take the filter down and look up inside the air conditioner. If you can see the coil, see if there's anything like a coil of very small tubing hanging in there next to the coil. Also make sure the cool discharge air isn't able to take a shortcut back into the return air.
