Depends on your motorhome which is? I have added Air bags to my 32H, I'd guess about 2.5"...3" max. I only adjusted the air once as the hyd. levelers work most of the time.

Well.
We'd need to know the coach brand/make/model/engine etc. and, what kind of leveling system you have. I.e. Air suspension and leveling, or, air suspension and Hydraulic leveling etc. Your question is a bit vague.

Looks to me newer big coaches made by all manufactures have low road clearance and those equipped with air level only are not fit for boondocking off road.

3 to 6 inches max are about normal for air leveling. look at your air bags. that should give you a good idea about your limits.

You are correct.....the new coaches are very low. We have seen the same thing and I measured a few of them inflated and deflated (about 3")

Like the others, I haven't actually measured it, but agree that air bags can't make adjustments as large as jacks can.

There are two times when mine hits maximum adjustment side-to-side and front-to-rear.

On the road in front of my daughter's house, the road slopes about 6 inches over the width of the coach. It does a fair amount of creaking as it leans to the left, but it does get level. Both my wife and two-year-old grandson have difficulty climbing into the coach when it's leaned that far.

When entering a driveway that slopes up, the trailer hitch sometimes drags. For these, I get a guide to let me know when the hitch is about to touch down. I stop, put the coach in neutral and put on the parking brake. I then lower the front as far as it will go and lift the rear. My guide tells me this lifts the hitch about 10 inches. I can then immediately move forward before the coach gets completely back in travel mode.

The coach is 40 feet long, which means my left-right and front-rear numbers don't match.

I also level the coach to fill the fuel tank, if it isn't level, the tank either doesn't get completely full or it leaks fuel from the low side.
