Welcome to the skoolie forum, King John! Step right up and take your seat on the throne, for with that bus you are for sure the King Of The Hill!
Now you just have to replace that noisy "Screamin' Demon" two-stroke engine with a grunty modern four-stroke, such as a Series 60, and you'll be Emperor Of The World.
I'm surprised at the Gross Vehicle Weight Rating of 37.400 lbs. This would easily make the axles heavier than legal, and the tires heavier than their rating (also illegal, of course, but more importantly unsafe). The maximum weight on one axle is 20.000. (With four tires, this is safely within the limit of the tires.) So let's assume you have 20.000 on the rear axle. That puts 17.400 on the front axle. Most vehicles, like the 18-wheelers I drive, are limited to 12.500 on the front axle. There are exceptions, and buses and/or RVs may be exempt, I have not looked into it. But at 17.400, the two tires would likely be grossly overloaded. A pair of the common 295/75x22.5 can carry something like 12.350. So your bus would have to have much bigger tires. I rode on a Grayhound a couple of years ago, and noticed that it had monstrous tires -- something like maybe 335/75x24.5. I'd have to look that up also.
So you might want to take a close look at the tag with the weights and tire sizes. And the numbers on the tire sidewall. And please tell up what you find.
Easy air tank drains can be installed on any bus. You just replace the old drain valves with spring loaded ones with a long cord to pull on. Costs maybe five bucks each. I replaced all four of mine with these.
Now... WHAT DID YOU PAY FOR IT?????
