Cheapest way into a 24 ft Quantum with a real corner bed and corner bath. No slide-outs, read from the floorplan drawing: compact class C body, queen bed/dinette/cab-over bunk all within one straight-walled envelope. Only the presence or absence of a slide is taken from a drawing, never the number — a blind control over 76 floorplans with known counts got presence right 72 times out of 72 and the exact count right 26 times.
