Thomas HDX: Anyone build one? I have questions?

Hi Guys, I am getting closer to making my first bus purchase and settled on the HDX and need some help with inside workable dimensions from behind the steps to the existing rear wall over the engine bay and also the interior workable width.
I would like to communicate with bus owners who know a few basic answers such as that. To be clear, I am speaking about the 40' bus.

I have the predecessor, the Saf-T-Liner MVP ER

It is 35 feet from the rear edge of the stairwell to the back window.

Mine is the 140 +10" ... that is, 14 body sections (windows) plus 10".

A word of caution:

This model has an electrical issue with a recall. The issue is the battery cables were sandwiched between the body and chassis at the factory. BE SURE this problem is solved BEFORE you buy. A school district I worked for lost FIVE of these buses due to this issue alone.

In addition to that be ready to rebuild the dashboard. The plastic used to save weight on the bus is in the sun due to the large windshield design. All of these buses I drove had issues with the dashboard buttons and whatnot breaking due to dry-rot.

One final note: notice how the rear view mirrors have only ONE solid connection point. These mirrors tend to vibrate from the engine/road/whatnot vibrations from general use. There are reasons why Thomas did not continue this design. The mirrors vibrate to the point they are useless in backing, passing, and generally any kind of use. Parts for these mirrors are used from a rare alloy called unobtanium - good luck in finding parts. You're better off converting those mirrors to more standard configurations with common parts.

Just my two cents for what it's worth.

Those mirrors always remind me of an old stud bunny I used to have. His ears used to droop like that just before he called to his harem, "NEXT!"
Then they stood at attention again.

Interior width is like my '89 Thomas. 7' 6", actually just a bit shy of that.

Thomas HDX

Hi, I work in the parts department at a Thomas Dealership. A few words of advice in dealing with these busses, basically all of the flatnose models (Engine Rear and Front) can be difficult to work on to say the least and parts get pretty expensive. Another issue with these busses is that they are not nearly as universally equipped as the conventional models. That being said the size advantages to these busses had me thinking about one for a conversion for a long time, but I finally settled on a conventional. Let me know if you need any help figuring out parts and I will do what I can!

Thanks for the offer.

What do you mean about not as well equipped? Mine seems to have about everything I could have wanted.
