My partner and I bought this bus a few years ago, hoping to live in it full time. Our dream was to work on farms, regenerating soil and sustainable systems, with a caravan of other earth-lovers. Here’s a link to the permaculture design project we created to support this idea.


We named it the Box Turtle Bus because we’re biomimicry nerds and loved the fact that box turtles have some of the strongest shells, which is another reason we bought a bus – they have the highest safety ratings of any vehicle on the road – they’re designed to carry children!


We have since found another place to live together, and have decided to put it up for sale.  We’re hoping it ends up with someone who can really utilize it. It has been well maintained.  We did a lot of research before settling on this particular year and model.


We wanted a mechanical engine, before the computerized systems that so many diesel mechanics warned us about, so we found it!  We also wanted it to have an Allison transmission, and an engine that is capable of being converted to run well on biodiesel. This bus has all of that, and at 102,000 miles, is still just getting broken in.  Mechanics say it will last many more decades.


This skoolie was designed and used like a mobile cabin for a group of friends before we bought it.  When we got it home, we had a strict enhanced inspection done, getting it in tip-top shape, including all new tires – an important foundation for longevity.


Since then, we’ve kept it well maintained, taking it on short drives and local camping trips.   It sleeps 6 people currently.  There are two bunk beds with full size mattresses and a pull-out couch bed with comfy padding.  We hope it finds a good home with you!


We jumped through all of the hoops to get this bus tagged as a motor home so that you don’t have to!


This skoolie has been insured by State Farm for about 4 years now.  Getting skoolie insurance is another hurdle that many school bus owners struggle with.  We did the work to get it insured as a motor home!

The toilet is a DIY composting toilet – a framed out wooden box with toilet seat containing a bucket which is easy to remove from a hinged door. We will add a bucket of biochar for you to get started too.  Biochar makes waste odorless, easy to remove, and bioavailable for building healthy soil.



There are 2 super sturdy bunk beds bolted to the bus frame – each with a full-size mattress.  The couch also folds out to a full mattress-sized bed, and there is storage space under the couch as well. This bus was built for a group of friends to get into the woods to hunt and camp for days!


Penny table

This is a fun table/counter/bar top.  It was made by the previous owner.  It contains hundreds of pennies in resin and is easy to clean. There’s a game he created as well: 5 pennies are reversed – can you find them all?



Optional large woodstove can be included.  There are cinderblock bricks installed in the flooring to mount this over.



Wall mounted Vizio television, across from convertible couch (with storage under, turns into bed)
