The interior of the Glastron is a study in compact functionality. Product literature states that the Glaston sleeps six comfortably in 3 double beds, has a gas/electric refrigerator, 12-volt and 110-volt power, and fully self-contained bathroom. By the 1970s, most travel trailers and motorhomes had plastic veneers applied to particleboard, thus this Glastron is a real gem since its interior is sheathed in red oak.
