Air Leak in Auto Level

[tireman62075]

2005 holiday rambler scepter 40' pusher
air pressure used to hold a couple weeks, now it goes down in 2 - 3 days . it has the firestone intelllride air leveling system . it use to remain level while parked even when the air tank went empty . now the passenger rear bag is losing air . I am in rgv texas for the winter, don't really want to get under it without some jack stands . any advise on searching for the air leak from someone that has experienced this before would be appreciated .

Thanks in advance for any thoughts

Take a spray bottle and fill it with a bit of dish soap and water. Give it a good spray and look for bubbles. With trucks and trailers I found if they had some time or mileage on them a lot of times the leak is around the base...but it could be anywhere and the soapy water will tell the tail.
Also give the air line a spray.
Good luck
