Attaching a table to the trailer.

[tyler811]

Looking to attach a table to the trailer using the 2 piece sliding table support. I however am not sure where to find the studs in the wall. I have a stud finder but interestly enough it goes off whenever I pick it up. [emoji38][emoji16]. Ok sorry, it works on drywall and wood walls but not metal.

Any idea on how to find the studs in the wall? I would like to attach it right above the wheel well just to the left of the power outlet. About where the blue line is.
