Turning Radius in a Parking Lot

[sns777]

I need to check if a fire truck can maneuver into a driveway and parking lot. I do not have a turning template for this fire truck that I can overlay onto the plan. I also do not have truck turning software. I do have lots of info on the fire truck, i.e. minimum turning radius, wheelbase, bumper swing radius and inside radius as well as overall length and width. How do I do this?

I usually use an AASHTO "City Bus" for a fire truck, but my tolerances aren't that tight either.
