Can you inflate a low air bag by hand

Never done so, but you can air up the wet tank by installing a valve and air coupler and use an air compressor. Is your onboard air compressor down?

I can on my '09 Country Coach, but only because I had HWH install their Active Air system. As part of the system they put in air lines and schrader valves to individual air bags. Before that there was no way to add air to an air bag. If yours are low then perhaps your ride height valves need adjusting or replacing?

….same question...."inflate a low air bag".....meaning the other 3 bags are ok--more information please?

Please tell my about ride height valves

[Old Scout]

….as mentioned, individual air bag height is managed by individual ride height valves on each corner. Proper height is determined by a combination of factory specs and distribution of weight on each corner....Most, but not all, Alpines "suffer" from some amount of air leak-down over time, so if air bags are inflated, jacks are up, and engine is not running, some degree of tilt or sag will eventually occur.....there is extensive information on this forum about air leaks and ride height adjustment….

Thank you sir where might find the data to do this

[Old Scout]

...start by using the IRV2 search feature above to see what has already been written on this forum....try the search string "f104/ride heights"... I will post the ride height specs shortly but the search will provide you with specific instructions for how to measure between the axles and the frame to apply the specs.....

[Old Scout]

...front axle height is 10 5/16 + or- 1/8 inch.....7 1/2 for rear axle [example: measured from bottom of frame to weld seam on the middle of the axle] …..front axle measurement process is similar but more complicated to execute.....
PS--these specs get you in the ball-park but I am a firm believer in getting a 4-corner weight done so you can use this info to fine-tune the ride heights...

Our air bags will bleed down in about two weeks, and yes the LR is the first one noticeable. I just dump the air and keep it on the jacks long term now. If the coach is low on one corner when roading then yes, a leveling valve adjustment may be in order provided your four corner weights are reasonable. Good information provided by OldScout is correct.
Active air would be a nice upgrade I suppose, but air loss over time is not an indacation of a problem. Even with active air unless you start the coach every week it's going to sag eventually. That's what the stabilizer jacks are for, correct?
