ORED ride height

What is the correct way to measure ride height on an Oshkosh chassis? My rear end appears to sit a little lower than the front end.

Hopefully you will be able to get the "where to measure and the correct dimension".

Apparently this is one of those "ageless" questions.  Here is a blast from our Forum past:

Correct ride height for '91 Grand Villa on Oshkosh chassis?

Sorry, I can't help.  Even a quick Google search doesn't enlighten - most answers I found are variations of the phrase: "Ask the chassis manufacturer for the specs".  Big help when the company no longer exists.

Just for my own curiosity, can you refresh us on how your coach is suspended, front and rear?  Springs, air bags, torsion bars, or some combination of those methods?

Good luck!

It's the traditional 2 airbags at the center of axle and shocks setup.

I have the Oshkosh service manual for my coach and it seems even their writers tried to punt on the  question.

Really hard for my to find somewhere truly level to check where I'm at but I suspect it would be pretty level, yes. If it is out of spec it's probably not by much

Elliott,

In the absence of the real answer, another "pretty good guess" is to measure shock absorber compressed length and also extended length. Put ride height slightly higher than half way between those numbers.  Critically, this assumes both OE design shocks and that they were speced properly to begin with.

But, it will give you another indicator.

So my coach seems to be exhibiting the same behavior as the two guys in the thread Chuck linked to. Slightly lower in the back at ride height. En lieu of proper specs to adjust to Im going to leave it alone for now. When I get back this fall I'll put new shocks in and then see where we land between max extension and compression of the shocks like you suggest Brett

My fist fits above all of the tires .  Hang a tape measure over the top airbag plate and see what you have.  8.3 inch is. Close .
Then peek at the drive shaft angle .  That should be the main consideration imho.
