I don't have a lot of time for this project but I figure a small investment by me will provide lots of useful info to the people who know what they're doing.
I pulled the drain plug on both tanks and drained a sample into a mason jar.
There was no debris, no gunk and no moisture. Just clean, amber colored gas with only a slight turpentine smell.
Given the rate of flow I suspect there might be a lot of gas in there.
I put the mason jar to the marine fuel pump and it move fuels with gusto.
Then I reversed the hoses in an attempt to get the pump to prime the lines back to the tank.
That revealed a leak in the hose at an inline filter just forward of the tank.
Should i drain the tanks?
What do i need to know about Jacking it up?

Well, if the tanks are good, and there's exhaust on the way, all's left is brakes/bearings. And it soulds like it can be driven to its destination. I('d leave the tanks full - if they got clean gas in alls neededd is check it and see if it's useabl;e. If so, run on it. If not, at that point drain it and put new.
Does the master cylinder have fluid in? pedal go to the floor or stop?
Good news!

Good news, Dave. I would leave the gas in it. Your report says to me
that it will probably run OK on it. When I bought the X-PB, it had
run 12 miles in the previous 8+ years. When we cranked it up (with
only 1 muffler), it bucked, smoked, backfired, and required lots of
throttle to keep it running -- for about 1/2 mile. Then it backfired
loudly and began to run like a top. After a stop at a muffler shop, I
put about 30 gallons in it and we then drove it 400 miles with no
further problems.
Let's hope Possum Holler will do the same.
The gas line leak should be no problem to repair. Dependent upon the
appearance and feel of the hoses, they may need replacement, but
that's not a big deal if those on top of the tanks will just last the
trip.
Jacking the front of the GMC should be done at the center of the front
(main, under engine) crossmember. In the rear, jack beneath the big
casting between the tandem wheels. At either end, put jack stands
beneath the frame rails where they're doubled, just behind the front
and rear wheels. DO NOT get underneath a GMC without jack stands. If
a air bag blows or a torsion bar lets go, there's not room under there
for you.

Just thinking that a great name for Marsha's coach would be "POGO Possum"
after the comic strip by Walt Kelly of the same name. Probably back before
some of you out there were borned. One famous quote by Pogo was, "Albert,
don't take life too serious, 'taint nohow permanent." <Grin> When my son
Christopher was 4 or 5, he and I would spend every sunday morning laying on
the living room carpet and reading the sunday comics. Katzenjammer kids,
Smokey Stover, Pogo, Tumbleweeds, Smiling Jack, Mary Worth, Steve Canyon,
Dick Tracy, Lil' Abner, good serial comic strips. Both of us used to look
forward to it. Before he could go to school, he could read and write.

Here is what I would do:
1 Fix the leaking hose
2. Replace the inline filter near the leaking hose.
3. Replace the filter in the carb.
4. Install an additional inline filter in the hose between the steel line on the frame and the input to the mechanical fuel pump.
5. While you have the above hose disconnected, I would turn on the electric fuel pump and let it fill up the lines to the mechanical pump.
6. Start it up and drive it home. I know you have several other issues to address before it is drivable.
7. Carry spares for all three of those filters.
On the coach I brought back from California I had to replace BOTH filters twice in a little over 2200 miles. Even though the first filter caught most of the rust, some of it traveled through and got caught the second one.

Ken,
With all of your experience driving the unknown coaches, I think your recommendation has a great deal of credibility.

The reason I suggested the added filter up front just before the mechanical pump is in that position it would catch anything that might loosen up in the old hoses. Without it everything would be caught in the very small final filter in the carb.
Carquest part number 86316 works well there. Wix makes the same filter but I do not have the number handy. It may be the same number for both Carquest and Wix.

Excellent choice. Put whiteboard under the front windows and she can put the name of a friend on each time they take it out, a la Kelly and his boats.
