I'm a day's drive from my coaches. I want to have a mobile mechanic lift
both coaches and swap the wheels from the Royale to the Palm Beach. While I
could lift my coaches blindfolded now, this will be a first time for him.
Is there a handy video that shows how to use the hook and best practices
for blocking?

Do you have a jack hook?

Jim K has the instructions on his site:

http://appliedgmc.com/images/bottlejackadaptor.pdf


however I doubt your mobile mechanic would use a bottle jack. You just need to tell him to jack the rear up by the bogies, and the front up on the main support that goes across. He should be able to jack stand at either location.

The tricky part to get anybody to understand is the use of a block, or barstock, on the rear bogies, to keep them from dropping as you jack upwards. it saves both the shock mounts, as well as you should be able to jack up minimally to get the tires off the ground.

Ugh. I've never used bogie plates when lifting these things. Have I hurt my
coach?

Guess I better order some? I dont' see them on Applied GMC's site. Where do
I get these?

If you have access to an air compressor, AND your coaches have Schrader
valves at the bags, the easy way is to jack under the bogie a few inches,
then deflate the bags. The tires will rise off the ground as you deflate
the bags. No stress on the shock absorber mounts that way. If no Schrader
valves, then use a flat bar through the bottom of the bogie box that
extends far enough out on either side to block the bogie arms from dropping
down.

What Hupy said. Jack under bogie and drop some bag pressure when partially
unloaded. For the fronts jack in the center of the main crossmember (there
are two holes in the center and you want the jack under them). Stacks of
dimensional lumber under the rear of frame as close as you can get to bogie
box without interfering with your wheel change and a pair of jack stands
outboard of the jack after the front is in the air. With one coach cribbed
up the mechanic can work off the jack on the other coach one side at a time
in the rear and once for the front.

I doubt you had done any damage. The shocks are pretty stout. But I would guess you had to jack the dailights out of the side of the coach as the tires just dropped and dropped, before they started getting airborn.

The plates I have seen are all home made. I just a chunk of steel, others use broken leaf springs as the pictures stolen, and others I have seen use pieces of wood. The idea is to not allow the bogie to drop down when you jack up.

here is a picture of a piece of wood doing the same thing:

Just be sure to let the air out of the air bag before jacking the wheel off
the ground. I have 2-1/2"x3/8"x14" lifting bars. One has a distinct curve
in it from having forgotten to let the air out. Also important if you use
the aluminum blocks which someone was delivering several years ago. I've
seen one bogie which was cracked at the bottom from using those with air
still in the bag.
