Arrow Chevrolet Express 3500 School Bus - Interior sizes?

Hi Everyone,

New skoolie hopeful here!

I've spotted a Chevrolet Express 3500 school bus (6 windows) up for sale which looks ideal for a first conversion project, however, the seller hasn't specified the interior sizes and the bus is too far away to view in person unfortunately.

Feels like a waste to send a mechanic in to check the engine over if the sizes aren't right to begin with, so can anyone in the know help me out with the following dimensions?

Interior floor-ceiling height
Interior width
Interior length from back of driver's seat to back of bus (approx based on 6 windows)

Bonus points - The bus has a 6.6 L GM Duramax Diesel engine with 'automatic transmission' (described to be in good condition). If anyone's up for sharing any experience / advice on this particular engine, that would be much appreciated.

There's 220k miles on the clock and the vehicle year is 2007.

Look forward to hearing from you!

Curious if you ended up buying the bus or checking it out? I'm also looking for the interior height of the same vehicle, and struggling to find anywhere that lists it.

The cutaway manufacturer, in this case Chevy, doesn’t manufacturer the bus body, so you need to know the bus body manufacturer.

You can’t really count windows to derive the length. I have a 5 window Thomas Minotour. It’s 14 feet long behind the driver seat. I measured a 6 window Collins when I was looking at buses and it was only 6 inches longer.

My Minotour that was built as a wheelchair bus has a center height of 6’2”. I think the Collins buses are taller inside and they have a flatter roof so more uniform side to side

Exclamation 2008 Chevy Collins/Midbus 3500

I’ve been searching for the height of a 2008 Midbus. I found out that Midbus is now Collins. I know what chassis I have so the attachment helped. The height seem to be the same… height at center is 77”.
