Screwing into outside walls

Hello All - please forgive me as i am totally new to this RV thing. I recently bought a 1997 fleetwood tioga 31... I want to convert th "closet area to have more shelves and screw into the outside wall and the inside wood. The inside peice is no big deal it is particle board and that is easy enough. But the outside wall is my question.

Can i run a screw into the outside wall, what kind of screw should i use, and how long of a screww should i go with. I basicaly want to make a extra shelf fr storing clothes...
Thanks

    I "second" the idea of lining the inside of the area with another board and screw into that. Use Liquid Nails to hold the boards to the wall. The weight of the cloths will then go down the board and not the wall, which is very flimsey and thin.


    Yep this is the best approach.
  • We wanted shelving in our wardrobe cabinet as well. I simply fastened small 1x1 pieces of wood to the backside of the wall that the wardrobe door was on. This supported the 1/8" plywood framed on the underside with 1x2. To support the back of the shelf (on an outside wall as well) I ran 1x2 strips of wood in a vertical position from the floor to the bottom of the lowest shelf and between each subsequent shelf thereafter . To hold these blocks in place I used sticky back velcro. I liked this method because they can be easily removed. A little over 2 years of use like this has worked out great.
  • I don't understand why this requires doing ANYTHING with the outside wall.....and think that probably would be a BAD idea.

  • You might get some ideas of what to use by looking at other hardware screwed into the outside walls, such as window blinds/curtains, dinette table brackets, etc. On my motorhome, these are generally about inch long screws.

    Don't expect a vast amount of holding power from the wall structure; it's probably just luan (cheap thin plywood) attached to a styrofoam core. A well nut or some other sort of expanding fastener would give greater holding power. (It sounds as though your stress will primarily be in shear across the screw, parallel to the wall surface, which doesn't require too much holding power.)
  • I'd use 1/4 or 3/8 plywood and "line" the closet and hang my shelves from that.
