Hello everyone! I am super stoked to say that after years of wanting to jump into to making a skoolie, I have taken my first steps and purchased a bus today! Looking forward to being a part of this community and sharing the journey of making it into something super rad! I am sure I will have questions and can already tell there is a wealth of knowledge here. Some pics of Gladys (the bus) are provided. Let me know what you guys think of the old girl! Cheers.

1995 GMC Medium/HD Trk B7 B7T042 6.6L Turbo Diesel 6cyl

Nice and already has a paint job. How she look under the bus and inside? Much rust?

As picky as I am about things, I agree you can/should keep that paint and focus on everything else as it's def "good enuff" for our purposes

Picker her up this weekend, kind of.
Had a 7 hour trip to get home. The Body is in pretty good condition minus a small rust hole in the floor by the stairs and a heavy black mold presence on the seats.
I took it straight to a mechanic for a once over before attempting the drive home. Checked all the fuel levels and got a piece a flat metal to patch the floor. I wanted to replace the fuel filters as well before making the maiden voyage but no where was open on a Saturday morning there.
Once I hit the highway my top speed was about 45. 50 or so on a good down hill. The mechanic told me the rear gear diff was a 4.11 which made sense for the low highway speed.
7 hour trip home is now a 12-14 hour trip home though.
At about hour 3 of the trip I noticed a dip in power happening.
Hour 4 or so it was getting worse. I started calling ahead of us looking for fuel filters and found them about an hour ahead.
As I pulled up to the place with the filters at hour 5 the bus died. I swapped them out and bled the lines. The old ones were full of gunk and algae. I suspected the hours of bumping down the road in a long sitting bus had shaken loose debris in the tank.
After some gentle coaxing (Two cans of starter fluid and cuss words of encouragement) she roared back to life. It took about 2 hours all together.
We continued our journey for another 2 hours and came to a leg of the journey that consisted of long uphill stretches with small flats. Each hill stole speed and nearing the top of the last one she rolled to a stop and died. I had to roll it back to the flat in nuetral to get it to start and had to carefuly work the AT545 transimission shifting with the gas pedal to clear the hill.
At this point we hit a down hill and were cruising and the bus started to smoke white behind us pretty bad. We pulled it into a travel stop and it died again as we pulled into the parking lot.
I suspected the the fuel was gunking everything up and starving the engine of power at this point. I checked the bleed bolt on the fuel line and it bubbled, not sprayed. Now I am thinking maybe I am airlocked and didn't get all the air out before. Bleed the lines again. Black sprayed out of the return line. Oil in the fuel. I called a vehicle shipping service and had it towed the rest of the way.

To outside eyes this might feel like a horror story, but I was always prepared for the engine to have major problems and the bus to need towed to make it home.
I have a project on my hands for sure, but for 1000 dollar (2800 now after the tow and parts) 1995 bus with 467k miles it did better than I expected. She made it over 7 hours which is what the trip was supposed to be.
Definitely had a blast with my buddy on the trip. Bus should be here tomorrow or the next day.

Making memories.
 
What engine is this-- a Duramax would be a V8-- and I would never have thought they put a Duramax in a bus. Just curious.
 
She looks nice, hope it serves you well! I don't know if you have ever driven a large vehicle before, but my advice is simple. Think of it as a longer and wider car that's slow and handles a little worse. Other then that it should drive similar.

This should be your profile bio lol

Sounds like you've got the right attitude about it. We just brought our bus home yesterday and I had some similar issues, though far less catastrophic.

IANAM, but it sounds like your fuel system needs some major TLC. Given you've had it towed to a secure destination, you'll get it sorted out in due time. I'm sure you'll be doing much more than fuel filters as you tune 'er up.

I don't want to beat a dead horse, but the AT545 ain't doing you any favors. You probably know this but it bears acknowledgement. From what I have read, dogging them up hills is what fries them due to a lack of a locking mechanism in the torque converter. Have you considered swapping to the 646 or something better? Might be worth putting the resources for the rear end swap into that instead. Just a thought.

Cheers and good luck with the build. I'll be following as a sort of Skoolie cake-day compatriots.

Edit: All that being said about the AT545, you'll find members here that are perfectly happy with theirs. I believe Chuck Cassady's current personal bus has the AT 545 and he did swap the rear end, so it's definitely a YMMV situation.

Hey! Congrats on getting your bus home! Solid suggestion on the bio and it will be implemented after this message.

I have put some thought in changing the trans to a 646, but felt I was putting the cart before the horse. I need to get the engine rebuilt, then I can drive it and truly see how she feels. It's a high possibility that I do make the swap though down the road.

Sound logic. Also probably best to find a "G" before doing much else [;)]
