My MH was built in 2001 so that puts my airbags at 22 years old. I have air leaking somewhere, so should I have the airbags replaced first and see if that is the problem or pay the shop to search for...
What chassis is your MH on? Air bags didn't last long for me. If in coils springs rocks getin an puncture holes. On my P30 I replaced front springs and air bags with variable raye springs.
