front right air suspension loses air
my suspension in the front right (passenger side) does not
hold air and does not seem to build up as much as the other side.

Check the right rear HCV adjustment and look for leaks too. Side to side levelling is accomplished by the two (2) HCVs on the drive axle and the one on the front steer axle only raises or lowers the front of the bus.

Airbags been replaced? Because the way the exhaust is routed on a 3208 the curbside front airbags will fail first. But if airbag is bad I bet you wouldn't be airing up at all.

the. and are relatively new and i’m wondering since it only has one valve in the front and 2 in the rear if the one in the rear on the same side has any relationship with the front on same side. the other thing is the gauges read zero on the dash as to air pressure but the suspension is still say half aired up. it’s been a struggle. not life threatening but frustrating

thanks dick that is good info. not sure
why she settles so fast and why the gauges go down to zero before the suspension hits it lowest but i will focus on the rear leveling valves too

What is the status of your front and rear panhard rod bushings? If they are warn then the bus will lean. 1984 I believe has adjustable HCV rods and one may need adjusting, which one? Probably in the back on the same side the bus is leaning. Air systems will leak down while parked and that may improve with use, but, check air tank drains, does your wet tank have spitter valve that needs to be replaced? I dont have a air drier on my coach so I dont know a ton about them but they can leak. Step valve and generator valve can leak too. Check the front airbags for leaks , recent replacement doesn't mean they can't have a issue.
