Paul, I sent you a PM today, and here is a follow up on my dash air system that was charged today. It took 2 gallons of R134a refrigerant, my mechanic put a temperature gauge in the dashboard vent and it was reading 46* on the psi and he said that 200 was high and 60 low. Good Luck with your system. Take Care, John

thanks and I'll be watching for that report.
I'm a career do-it-yourself.

as teachers pet noted, his unit had a 30 foot line in the system. there is the main problem with using weights for recharging motorhome systems. the hoses are added by the manufacturers, and some have no idea how long they are. and they vary from model to model. so weight numbers supplied are a hit or miss situation.
if you have partial cooling, there is a 95% chance of no leak. just add some freon with a dye and check it with a uv light days later.
if there is a leak, repair it, evacuate the system, and recharge it, using the pressures as a guide. you can get a vacuum and the guages,at autozone on loan.
when the pressures are near what they should be, check the sight gauge if present. keep adding till it clears up, or the a/c cools to suit you.
i know this is a backyard mechanics approach, but is works for me, and i have used it with much success on all my coaches. just dont over do it with the freon. moderation in all things.
having said all this, most of you know that the dash air does a poor job of coolng the whole coach.
i use the generator and run the basement air on my meridian dp. it doesnt affect the mileage that much. no more than running the dash air. all of it takes fuel.

Most times there is a sight glass in the liquid line. It should be clear. Clear would mean it's fully charged and all liquid is passing by or that is completely empty. If you see bubbles, it may need more Freon especially if it is nearly all bubbles. If only a few bubbles, the system probably has enough.
