I'd think this varies by manufacturer, but...
Our Jayco Class C has a frame of rectangular (about 1"x2") steel, welded in a grid pattern. So in Michael's picture above, there would be lengthwise pieces spanning those crosswise beams. Styrofoam insulation inside the rectangles formed by the steel. OSB used as flooring on top, and a sheet metal skin across the bottom. Look up from the bottom and you see galvanized sheet metal. Then inside, the vinyl floor covering is on top of the OSB. I don't think the OSB is much thicker than 7/16" or maybe 1/2".
Stud Finder is an interesting thought. If I thought I could cut the floor and put an access hatch over the in-tank fuel pump, I just might. But I would not want to cut the floor and find I was right over steel framing, or worse, here a lengthwise and crosswise frame joined.
