Keep in mind several responses you got are for HD Jacks ..not air leveling , using the airbags only to level the coach. I have HD Jacks( 1 of two systems) also but they are the older safari system that only goes from frame to axle .. nothing touches the ground. The airbags are very stable alone ,unless your doing jumping jacks ! Dropping the coach first I feel they are even more stable as the frame is resting on the axle at least before it levels . I've only used the HD jacks once .. never felt i've need them
Remember the Monaco is slides out first before you level or dump any air
