I did not opt for any reinforced walls mainly due to weight as Mary stated and did not feel the need for them. Most walls have framing inside the panels and seems to be sufficient in finding places to screw into if needed.

I reinforced the bath/bed wall in the E21 for several reasons, I install teak towel racks in the bath and magazine rack and miscellaneous on the bed side. Reinforcing that big wall allows unlimited positioning of items as well some structure help up front.

We didn't reinforce our walls on our 21'; however, I'm now wishing we had reinforced the wall by the closet. The TV arm we purchased from ETI doesn't hold the TV as snug as the one we had on our 19' so buying and fitting a new arm is going to be trickly ...
