Project Tina - Skoolie for a Family of 9

I thought I would go ahead and start a project thread.

Saturday (17 Feb 201 we pickup up a 2004 Thomas 40' with Cat 3126 and Allison 3060. Bus has 140k miles and runs great! I am crossing my fingers and hoping we can get that 6th gear unlocked in the future.

Our plans for this bus is to be our full time home for sometime while we build a house.

We will be fully insulating it with closed cell spray foam.

Plan currently is to put a queen master in the back, bunk room, bathroom, kitchen and then living/dining room.

My big dilemma is I really want to do triple bunks but will not be able due to the low ceiling height of the bus.

If anyone has any tips or ideas on fitting all this into a good layout on a 40' bus please let me know.

We will post regular updates on this project in this thread and also regular video updates via YouTube.

I am actually pretty excited about this project.

Oh, did I mention we are on a slight time crunch? We are hoping to sell our current home by May, Pay off all our debt and leave with plenty of Cash equity to get us started on our debt free/mortgage free future.

This means I need to have the essentials completed in the next few months....

Current Progress - Seat removal in progress, Interior Panel Removal in progress

Hi,

I just started the process of having 6th unlocked on a very similar bus. The good news is that Thomas seem pretty reasonable about this.

The bad news is that it might depend most on the Final Drive Ratio of your rear axle. Seemingly, if unlocking 6th would allow over 75 mph, they might say "No".

I have heard of one bus with a 6.14 ratio being unlocked (another Saf-T-Liner with a CAT).

Mine is 5.38, and as far as I can tell it could be right on the limit depending on tires.

So ... what is your FD Ratio?

I am not sure actually. Would the Final drive be stamped anywhere on the differential or data plates somewhere?

I have heard that Thomas will still provide the permission slip but request a speed limitation of 75 be programmed in.

Yes. The ratio will be on a metal tag attached to the differential housing.

Mine was missing, Thomas told me what was fitted in the factory and that computed with the speed and RPM I was seeing.

My engine is mechanical, and can't have a top speed programmed in. It's limit by rpm in the injection pump.
