When you go see it, get as many pics and video as you can.
Try to provide as much spec info as you can.
That way people here can give you a better opinion.

I can only offer you limited info based on what I've been reading.

You say you want to drive it to San Diego, up to Sedonna, and eventually perhaps across the country. You won't do that with a gas powered bus. 55 MPH will be about the absolute top speed you could hope to get out of it regardless of the rear gearing. I would not be surprised if the rear gearing only gives a top speed of 47 MPH. Also while chugging along at slow speed you will be stopping at every gas station you come across just to make sure you don't run out. 2-4 MPG was pretty typical of the gas powered buses with automatics we had back in the day. Even if it had a stick shift we would have been thrilled to average 5-7 MPG.

The other real problem with gas powered buses besides being slow is when you get to a hill you will be poking along in the break down lane with your hazards flashing as you climb every hill at 25-30 MPH.

You may think I am kidding but I have driven enough of them to know they shined on routes where the speed never went over 35 MPH but were next to useless if we had to go a long way.

Of all of the gas buses the worst were the Fords (regardless of engine) and the Chevy/GMC buses with small block engines were next to the worst buses. Chevy/GMC buses with the big block engines were a little better at making speed and climbing hills but you paid for it in greater fuel consumption. The gas powered IHC buses were the best of the bunch and the kind with which I have had the most experience. But I wouldn't purchase another one if I had to drive more than 30 miles round trip.

For what they were they were not bad buses. But when we got the first bus that had a DT466 or Cummins 5.9L we wondered why we had waited so long to make the upgrade. While most of them still had top speeds of 55 MPH, they would pretty much do that speed up any hill until you got to the steep parts at the top of the mountain passes. And the best part is the fuel mileage went up to 8-12 MPG.

Good luck and happy trails to you!

I really do appreciate the advice, If you all are saying its a NO NO...I'm taking heed to that. I found a 1989 Thomas, GM 8.2L diesel, 44000...sounds better I'm hoping!

Will do, and thank you. I'm going to see it in a few.

The 8.2L is a step up from a gas engine but not a very big step up.

Most of those were set at 180-210 HP--not a lot of horse for such a large bus.

One thing to keep in mind is that an inline engine will out perform a V-type engine on every hill. While the HP and torque ratings might be similar, in the real world V-type engines do not pull as well as an inline engine.

In other words, a 190 HP Cummins 5.9L will do circles around any bus with an 8.2L that is rated at 210 HP.

Is there a particular reason why you are looking at such old buses?

For the same $$$ you can get something a decade newer with more modern power packages.
