Jake,

If the ride height of your new GMC is set properly as per MM X-7525 | Section 4 - Rear Suspension | Page 4-34 | Figure 79 - Checking
Vehicle Ride Height the rear will be 11 11/16 inches from the ground to the top of the slot in the frame which is 56 3/8 inches from
the center of the bogies. You can't see this slot on the driver side as it is hidden by the Onan slide.

It looks like this: http://www.gmcmhphotos.com/photos/random-photos/p40040-rear-height-adjustment.html

Note the text under the photo.

Deducting 8 1/16 inches from 14 inches means you will need to raise the rear end 5 15/16 inches at the center of the bogies to get
the 14 inches there. That may or may not be enough depending on where the shipping company wants 14 inches. I suspect it will be in
the middle of the frame halfway from the middle tire contact point to the front tire contact point.

The shock absorbers limit the travel of the bogie arms so I would suggest that you drop the pressure in the bags very low leaving
just enough pressure to push the rear suspension down as far as it will go. Slowly jack up both sides and when the rear suspension
stops dropping measure the clearance from the ground to the frame and see if you've met the 14 inch clearance where the shipping
company requires it to be. If not you will have to disconnect the shock absorbers.

By the way I would highly recommend that this be done at or close the shipping yard because raising the rear end to the max will
affect the caster and could make your GMC a handful to drive especially at high speed!

Some additional items to consider:

1) The shipping charges will be calculated by volume Length x Width x Height. The guy I bought The Blue Streak here in Australia
from told me that the shipping company measured the width at the mirrors which added a lot of cost to the shipment. You might want
to get the measurements of your GMC from the shipping company to see what they're going to charge you. If they do measure it from
the outside of the mirrors you could ask your mechanic friend to remove them.

2) Take LOTS of photos of your GMC to show what it looked like when it was dropped off for shipment. That way the condition will be
documented for insurance purposes.

3) I don't know if your GMC has an awning or not but the guy I bought The Blue Streak told me that both the awnings were stolen
during transit so you might want to consider removing yours. If you decide to do that let the GMCnet know and we can provide
instructions on how to do it. There are powerful coils springs inside the awning that if not unwound carefully can cause injury.

They are back on road again, pushed arm back and bought couple new tires.
Next headache was waiting behind corner, shipping company claims that there must be 14" clearance under belly.
We planned to take airbags off and put threaded rods and pipes over them between arms for shipping.

Any better ideas?

Jake
