Bus Conversions done Professional


We can use any platform from OTR buses to smaller van bodied vehicles. The most common are OTR Buses [over the road] and activity buses.  Activity buses are normally used by churches and schools to transport people long distances in more comfort than a typical school bus. School buses are intended for a shorter ride time. Normally they will have baggage bays under the body, larger windows and more comfortable seats. Most of the OTR and activity buses are 102 inches wide. There are some that are 96 inches wide and some are 90 inches wide.  The wider body makes for a lot more interior space than one would think most interior height is normally over 6' floor to ceiling in these types of buses with some as much as 7' high.


  • We like to build tiny house styled homes on bus chassis. There are a lot of reasons for this.

  • Bus chassis are stronger than a trailer frame and will carry more weight safer.

  • Better brakes and suspension than trailers.

  • No need for a expensive tow vehicle.

  • You can pull a daily driver (toad) vehicle behind your house.

  • Better fuel economy and reliability.

  • And lets be honest here, they are just fun to drive.


We have built over 200 bus conversions and counting, with attention to detail and exact manufacturing techniques we build your conversion for years of enjoyment.

We have  buses in inventory that are ready to convert all have been stripped of all interior, roofs rises 2 feet mechanicals all checked and repaired. these buses are ready to design a layout and start building , no doors or windows added until design layout is for an inventory list of buses ready to build on.


we have buses in inventory that are ready to convert. All the hard work is done.


School buses are very commonly used. 
They are a great choice when your budget is low and the quality needs to be high. You can build a very safe and dependable motorhome or tiny house from this platform. School buses are designed to be in service for over twenty years and can last for hundreds of thousands of miles. They are most always 90 inches wide or less depending on the body manufacture. The typical interior width is 7'3". The over all height depends on what the school or church ordered interior roof heights range from 5'7" to 6'5".
