Qustion is to install the paneling with screws or staples?
Most likely paneling over OSB is not a structural issue. Yes, RV manufacturers use staples structurally, with no glue....yuk.
1/4" crown staples would probably get the job done just fine, the OSB is carrying all the load. A little TBII here and there to make it permanent. But, screws would allow you to disassemble the wall if you had to do any repair work. Glue and staples would make that job extra tough. Staples by themselves could be removed easier.
Staples would not be as visually noticeable as screws.
