Safe t Liner

[Metalriff]

HI I'm new the school bus conversion. I really leaning towards the Freightliner Saf T Liner style bus. Are there other models that have the same aero look? I will be making a toy hauler type of rig. I have access to a heavy equipment fab shop looking and to beaver tail the rear frame and install a ramp door. My buddy who owns the shop has done this before on box trucks , the skoolie would be new though. I believe the rear floor height is a couple inches lower than a standard dock height box truck?. Thanks Todd
