I bolted mine.
I don't take the camper off (for fear of being asked to "move" everybody and their mother). I used 4ea 1/2" x 2.5"L hex bolts and nuts with flat washers and lock washers. There's one near the door under the furnace, one two under the seat on the passenger side and one under the driver's side window. My camper interior was changed a bit by the P/O so you may not be able to hide everything, but I haven't had any problems - so far. If I get around to it I suppose I could replace them with Grade 8, but I think the bed floor or the camper floor will give before any of the bolts I have.
