Foretravel rubber mounted the body to frame.  You can see the pads if you look underneath.

Hence the height difference

As of yesterday I was told by a guy in parts at FT they are no longer interested in providing info for Oshkosh chassis.  Seems that Freightliner bought Oshkosh just for the military side of the business and we are screwed for parts.  This all started several days ago with those Bilstein shocks on E-bay, seems like a good deal, and from what I have found out they will work on a 4 corners.
Now about ride height, I went to my Oshkosh Service Manual which was a mistake, there are 4 pages in adjusting ride height according to Oshkosh.  I can scan them, but how do I download to the Forum?

After adjusting ride height at rear so that distance between the axle bump stops was equal. Got Jack's down. I will test Freightliner parts tomorrow when I order filters and other odds and ends.

How do you dump the air bags, tried dumping all air from tank valves, but bags must have good check valves as it set that way for a day and no movement.

HWH has a auto dump for the bags ,but you can wire a manual dump.  Find the front solenoid valve and the wire colors, same for the 2 back ones.  Now find those colors on the back side of the HWH control  panel.  Wire them to a push button switch, now you can manually dump the bags.  Notice that the solenoid valves have a manual shut off valve, with this you can dump the front only or the rear only or both, once you get it figured out it's pretty slick. Foe example right now the rear is aired up so I have access to the danmn HWH Jacks the I am working on, and the front is blown off so the shower will drain.

Second step of the auto hwh cycle is to dump the air after the jacks swing down  with the first push.

After that shut off the panel power. 

Yes the jacks are down.  I do not remember if there was a manual dump without the jacks on the auto panel

Will check for mud daubers nests on vents or other obstructions.

Phred,

I ordered all my belts, filters, thermostat from Rockauto.  Cheap fast shipping.  They were listed as Gates Standard but received Premium XL Green stripe for about $9 ea.  Wix filters for fuel, oil, tranny, hydraulics $6-$9.  Use 5% discount code 6556913558762115 if you don't have one.

Also they have a Gates tension gauge for $12.  Very valuable. Should test to 160 new, 120 used, acceptable range of 105-145.

Sorry to take so long  Phred.
 My front altitude; measured by hanging the  tape measure over the top air bag plate  and reading at the bottom edge of the bottom plate . Yes the tape has a sag as it passes the bag a little tiny bit.  8in.
 My shock centers are 15and 7/8 in.  I lowered the ride height a little to ride well with those cheap E bay Shox.  They range from 12 to 17 in.  15.5 or 15.87 should be a good place in bump with some extension.
 Moving the ride height a little should also run the bags in a new spot , maybe last longer.
 
AS far as mounting the shox;  You need a special bent offset dropped  wrench to hold the inner nut , right inside of the fuel tank .  Maybe the drop is the width of the frame edge , about 2in.    You can RTV the washer in place so that it stays long enough to fit the bolt back through .
 Once this nut is loosened the job is easy , all of my pieces came out easy .  For installing those 300psi Shox, I used a 1in rachet strap around the entire thing. Turning the wheels to one side and then the other opens up access pretty well.
 If you need to borrow my special wrench , send me an email  and I'l send it to you.
 To finish, you may need a half turn of the drag link to center the wheel.
