Power Gear air bag vs leveling Jacks

There are 3 systems
1. Hyd Jacks
2. Hyd Jacks AND air bag leveling
3. Air bag only leveling
4. The advantage to air bag leveling is you never have to worry about the ground situation(sand/dirt/mud) for the jacks to sink into. Both Air Bag and combo Jack/Air usually have a 12 volt air pump. Once you turn the Motorhome OFF and have leveled, the electric air pump will continue to air up the bags as they lose pressure and this will also cause the system to continue to keep you level.
5. You don't state what model Monaco, but usually the Hi line signature with Tag axles had the air only. The less expensive Monaco's had Air/Hyd jack. Doug

PS to your other question, Air bag and Hyd jacks have almost the same amount of lift available. The BIG difference is, with Hyd, and your site is very uneven you can install wood blocks under Hyd jacks to gain more lift.

The air leveling system works well. My only hesitation is, back when our friends had theirs, is there was still some movement in the coach you don't get with jacks.

I am extremely sensitive to movement so it bothered me - I get motion sick real easy, if you aren't then it's a wonderful system.

I know some units have both - air to level then jacks to stabilize. I would think that would be the best of both worlds.

BTW The tag bags are not used for leveling. The steer and drive axles can go up or down for leveling. Backing into your driveway the drive can lower and the steer raise and this may/may not be adequate to level (or close enough).

You should have tried the air bags. I think they are better.
For one the air bags system RV are lower to the ground than a jack system.

Had both and will take the air bags.

Push a button and it levels side to side and front to back. The leveling of course has mechanical limits. Very rarely did I need additional leveling blocks but if your driveway does then you'll know the next time.
