there are 2 different lengths of 55-59 "long bed", the 123" WB 3200 and 3600 have the same 98 inch floor, and the 3800 with 135" WB has a 110" floor .... in your "neighborhood of 100 inches" you have the same bed as any 3200 or 3600 of 55-59, different figures you see are likely measurements of different areas
