"23d" is a new dimension in RV travel

Is this a GMC?  Oh yes and so much more!

From it's humble beginnings to this prime example of what is possible with a GMC

As is the case with most of the machines we put together, the project started off with an idea and in this case the idea was how could a complete late model turbo diesel drive train be adapted to power a classic GMC.  Simply doing a "motor swap" is one thing, that idea by definition creates a "morphodite" machine that few mechanics would even look at for maintenance or repair.  No, this coach takes the idea of mating a complete late model drive train and chassis which any Workhorse trained mechanic can pull out the book and work with this machine.  This coach is actually and literally a mating of a leate model Workhorse LF-72 GM build Duramax turbo diesel motor, sporting an Allison 1000 5 speed transmission-- front wheel drive airport shuttle bus chassis  with a featherweight 1976 GMC 23' coach body on it's back!  Yep, what a combination!  And guys, what a project! 

I don;t mean to make this sound harsh but after building this machine, solving one impossibility after another, putting together a machine such as this is not for the weak of determination!  Mating these 2 major pieces together required processes never before attempted.  From stripping and redesigning of the original GMC body
