Strengths and cautions

Works in its favour

  • 78-inch headroom
  • Only two principal wheelbases simplify comparison
  • Up to 90-passenger body capacity
  • Current Thomas Type D construction and common-parts strategy

Check before you buy

  • Engine cover intrudes at the front
  • Newer platform means less long-term converter history
  • Exact published tire and axle data remain build-specific
  • Service access around a finished interior must be preserved

Will a bed fit crosswise?

Interior width is about 90 inches before framing and panelling.

Twin crosswise (75″) Fits, about 15″ spare
Full / double crosswise (75″) Fits, about 15″ spare
Queen crosswise (80″) Fits, about 10″ spare
King crosswise (80″) Fits, about 10″ spare

Similar platforms

Figures here come from manufacturer documentation, but bodies were ordered to spec, so two vehicles of the same model year can still differ. Measure before you buy materials.
