It should be in front generator area, probably on the PS. Look for the hoses going into the dash & connect into air dryer as well. There will be a connection to add freon there.

On my 2003 Monaco Dynasty the high and low pressure ports were in the rear (engine compartment) - near the a/c compressor. I had to un-latch the air filter and move it to the side slightly to reach the fittings. The only correct way to fill, is to evacuate the system, hold the vacuum for at least an hour, and then add the amount of coolant (R134a) called for. Mine calls for 4 lbs. Depends on the length of the MH and other factors. The amount should be in your owner's manual or a sticker near the ports.

You can use a pressure/ambient temperature chart to compare high and low pressures in the system to get close to the correct fill.

That's both places to look. Third idea is the coolant control valve to the heater core doesn't shut off completely.
The charts have been shared forgive me for not looking them up right now. The minimum to re-charge "since your might just be a little low" is a real set of gauges and accurate thermometer. Just using the dial gauge with temp wheel on cheap DIY can charge device and not the chart will put you over on charge, with thermal expansion valve used on MH.

Traditionally they are near the compressor or AC condenser. But you’ve probably got a leak somewhere. And that system will not be cheap to recharge? Probably close to 10ths 134A.
