Charger and air issues

Have had two new issues with my 08 Kountry Star MM Spartan w/400 DP that have just started to occur:
1. When charging the coach batteries with my generator while in storage, the Magnum LED will decrease the amp draw as the batteries charge up.I never let the batteries drop below 12.25 volts. In the past I've let the amp draw drop into the high teens and stop-assuming that reducing it to near zero wasn't worth the effort to obtain a 100% full charge. Recently the LED stops decreasing at 40 amps even with the generator continuing to run for upwards to 20 more minutes. However if I stop the gen and restart the amp draw immediately will appear to be in the teens with the stabilized voltage indicating a 95% charge. Essentially the LED seems to get stuck at 40 even though the batteries are continuing to be further charged. Does this happen to anyone else and does it indicate the system maybe starting to fail?
2.While in storage the air system psi will drop per the gauge, with the front and rear decreasing evenly over several days. However the front of the rv will actually remain at near full height while the rear seems to drop as indicated on the gauge. Essentially the front guage is indicating a drop which isn't actually happening. Any thoughts on how this can happen?
Would appreciate any thoughts!

Not going to speak to the battery charging, please search battery charging to get about a weeks worth of reading...

For the air systems, the suspension or air bags have a ride height valve that controls air flow into and out of the air bag.

Once at ride height, and if not moving the valve is "off", while driving the valve is constantly changing due to bumps in the road, this is why when parked you seldom hear the dehydrator dump, but then it dumps often while traveling.

Anyway, if the valves, bags and everything else is not leaking then the bags stay full, most will seep over time and the chassis will swuat down an a day or two.

Depending on your chassis, you likely have one valve in the center of the front axle and one at each rear wheel.

With the front only one valve, easy, in back if one leals a little then it shifts the opposite side causing it to open and drop the suspension down.

Whichever air system that drives the air bags gets depleated while the other one(s) retain their air as they are all seperated by check valves for safety.

On batteries, if they are taking a higher charge for a longer period of time then either the charging voltage is now higher or the batteries more discharged.

They will take a good amount of charge current while in bulk charge, then the current will drop off in absorbion phase, then when the voltage is correct it can be switched to float.

A constant voltage charger set to 13,5 volts will charge the battery correctly, but slower than others, in your case the battery is not even close to being charged properly and over time may loose some capacity, it will need a deep charge over a few days to insure fully charged, that will need a proper charger if left unattended.

Solar would be good investment for floating the batteries while in storage, current needs are minor if charged before storing.
