any advice on how to mount a sturdy shelf unit without destroying the luan. My father in law is a master carpenter, and i know he uses some strong liquid adhesives. what i'm looking to do in the front of the trailer is similar to this.. but with more of them. like a small workbench in the middle, with shelves and partitions on top and bottom of the bench. i think i can pre build it,then just adhere it or somehow attatch it to the front wall. i just don't want to poke through the outter skin of the trailer! also, i like the idea Doc Pete has with the 2 x 4's and clamps for the trimmers. would i mount them also to the luan, or how would you attatch them to a beam, self tapping metal screws? i have some ideas, but i like to do things right the first time.
