Hello Jon. Here are my measurements; Front; 14.5", Back 12.5".
Front is support point behind front tire and in about 24 inches.
Back is behind tag and in about 24 inches.
There is another support point in front of front wheels by tow hooks; 15"
My Coach is a 2002 XLII Chasis.
Paint is ok.
These support points are shown in the Prevost manual.
[QUOTE=Ray Davis;21880]Jon,
The 10.25 measurement I mentioned was directly in front of the drive wheel. I'm pretty confident of that measurement, and I believe my back end was up pretty high (I could slide underneath at that point near the drive wheel).
The front measurement is probably good, although perhaps as you've suggested, I may have gotten a little more height by first dumping my tag. I will check that out.
It would be nice to get another set of XL2 measurements. I do have a Prevost manual, but had run out of time, and wasn't able to spend time going through it looking for jack points.
Hi Ray. In the Prevost manual, under the section regarding supports and Jacking, there should be two topics. One discusses supporting the Coach Chasis or body. The other describes jack points under the axles in the front & back. You should have a total of 12 support points, half for the chasis, the other half for axles.
It looks like everyone is coming in all over the place....lets remember that a frame is a frame so the supports need to be under the frame. I really think that one size will work on all the bus's, but that's my opinion. Mine will work with one size, but I don't like waiting for my front to raise all the way up so my front ones are a little shorter.
Check out how this 45 footer is supported, maybe you long guys need 6 supports. I lightened then to show detail but I think that the front two on the rear is just to support the axles.
I must be measuring the axle supports because I get the same readings as Ray and I have a 91 XL.

Dale, Thanks...the posts look good.
As to six supports....I don't feel comfortable there because these stands have no adjustment. In order for six to work the coach has to hit them all at the same time when it is lowered.
Your right Jon, I would not like to use 6, you would have to use shims to get it all to be level.
I think that the 14 inch stand will work for all. I can't imagine ordering a set 13.25 and a set 13.50, we'll you get the idea.
The picture of my bus on 6 stands is because I was supporting the suspension in the rear, not the frame. I wanted the little extra height the air bags gave when they where overinflated.
I did measure the bus with tires on and the level low system as high as possible yesterday. The front is from the ground up to the bottom of the tow hook plates, 11.5"
The rear is behind the tag axle just in front of the transmission, there is a cross bar that mount to the frame and runs from side to side, from the ground up to the bottom of that bar is 12.5"
This is a 2000 XLII 45' shell.

I'm going to have to re-check mine. There's been a couple of posts about "behind" the tag, yet I didn't find a good place behind my tag. It could be that the 40 ft is different in this regard.Quote:

Jon,
I'm in for 4. I'll have to measure the H3 to see if there's any difference in height.
Thanks for making this happen.
Now I can stop using these guys.
